Why do I prefer it? This program has a lot of features and looks like "all in one" software. Once installing it, I am able to control the multimedia players from my keyboard, to copy and paste text using the mouse and much more. Each new feature does not require new components to install into the system - these features are included in one application. They can be activated or deactivated as I want.
This is the short list of the features :
the program is WPS-integrated
The system requirements are very low: OS/2 Warp 4.x with FP5 or higher. The Enhancer works with eComStation and with Aurora (Warp Server eBusiness) SMP. It creates more than twenty threads for its components and uses the SMP model as well as possible. It works together with Styler/2, X-Workplace and other popular software incorporated into eComStation.
Recommended hardware is: Pentium-100 CPU, 800*600*65536 Video. This may look like a joke, but it really is so. Enhancer performs all actions in the threads. Threads run with various priorities, sometimes as "idle", so it works in background and does not eat system time. I have tested it on the dual-CPU Pentium-166 and on the modern Celeron computer, and haven't seen any differences.
Memory used is: 0.3 MB for kernel + 1.75 MB for threads. Sometimes it requires more memory, but no leaks were detected. The memory marked as "for kernel" is the RAM volume required for event monitors - the program uses it constantly and it is always present in physical memory. The "memory for threads" is the RAM volume for program modules, it can be swapped to the hard drive if needed.
Looking into the sources (more than 3 megabytes of text in plain C language) you will see that the code is very clean and well documented inside. Each action has good description. The author uses his own language in comments (Russian), strong tabulation and margins. The program had been engineered in UML before coding, but diagrams are not available.
the Install window
The guidelines are easy:
Installer will modify your Config.sys file: the "LIBPATH" variable must be changed due to Presentation Manager requirements (for example, if you use old full-screen programs). Your current Config.sys file will be renamed to Config.nic
Information about features for the current page can be found in the program's manual. Just press the "Help" button to read it. The button has green font color
Another button is "Turn settings to the pre-defined state". This button has red color.
A little tool named "Viewer" is used by Enhancer to open documents. As written before, installation program detects software in your system, and viewer uses this information. It opens Mozilla or Opera web browser for HTML files and IPF Help Viewer or NewView IPF Viewer for help files.
The feature named "Smooth scrolling" extends scrolling in all windows. It is the patch for old text editors like OS/2 System Editor where you must click, move and release mouse to scroll window content. With this option window content will follow the scroll bar when you move it.
Another scrolling way - using arrow keys and <SCROLL LOCK>. With this option you can scroll window content using keys with arrows when <SCROLL LOCK> is turned "ON". This is useful for text editing and mail reading, I recommend you to browse mail messages with this option in PMMail reader. If you have a modern mouse with scrolling wheel this feature can complement it. As you know, scrolling wheel posts keyboard messages to the active window but does not really scroll it. With this feature it will always scroll the window content.
Drag'n'Drop actions are possible too. You can smoothly scroll window content using a mouse when button is pressed and <SCROLL LOCK> is turned "ON". You can choose another mouse button and pointer for this action.
example of Drag'n'Drop scrolling
This feature requires native OS/2 scrollbars so it does not work for applications ported from Unix operating system. By default this feature is disabled.
As you know each modern operating system allows user to change the window look. The Enhancer can redraw window frames using several ways. Frames and control elements can be repainted for all windows. In the settings you can select the "window theme" to specify drawing methods and parts of frames to change. All screenshots in this article can be examples for this feature.
You can suppress frame redrawing for selected applications and windows. If you want to keep frames in their default state you should use the "exceptions" in the Enhancer. Just point to the window and say "NO" and Enhancer will avoid to do anything with it.
Default exceptions are hard-coded in the program. For example, my favorite WarpVision player moves its titlebar and uses the free window frame place to draw movie control buttons. The Enhancer knows that and does not draw frame for WarpVision.
Rooms around the Desktop
settings for Rooms
"Virtual Desktops" are present in Unix and Linux operating systems, in OS/2 this feature was developed by Stardock ten years ago in their Object Desktop tool.There is possible to use the same feature in Nice-OS/2 Enhancer, it named "Rooms around the Desktop".
Each room is a set of windows, it has its own wallpaper and color scheme. In the room you can launch objects from your Desktop using WarpCenter or LaunchPad, and open running applications using the Window List. On the pictures in this articles you can see the LaunchPad and empty Desktop with background. These pictures were made by PMView in the Rooms where the common OS/2 Desktop is hidden (because it is a window as any other window).
For switching to the room you can use the numeric keys "2", "4", "5", "6" and "8" with the "Shift" key. Another way is objects from the WarpCenter:
WarpCenter tray with objects to go to Rooms
Here it is possible to use any other replacement for WarpCenter like X-Center and SysTray and switch to the Rooms from it.
You can assign some actions for various keys. For example, pressing a key you can launch the Window List, WarpCenter or LaunchPad, or any other object from your workplace. In the picture you can see how to assign WinKey to launch X-Center menu. It is possible to map one key to another or to the key chord, for example, you can post post <ALT-F4> chord to the window by pressing <F10>.
If you have a keyboard with multimedia functions you can use its keys to launch media players and web browsers and to control them. You can use three "power" keys at the right side of the keyboard and any other keys. Enhancer supports OEM keyboards like IBM Rapid Access or Compaq Internet Access. It works with Microsoft Multimedia and Cherry Multimedia keyboards.
Enhancer also allows you to define "Clipboard keys", known as <CTRL-C> and <CTRL-V>. They came from Apple computers and are used to copy text to Clipboard and paste text from it. Now these keys can be translated to common <CTRL-INSERT> and <SHIFT-INSERT>.
Other key features are placed in other settings windows. Enhancer can hold <Num Lock> in one state, always ON or OFF and map numeric keys to common "1..9". The Logitech and Cherry Business Line keyboards has a small key near left Shift and "Z" often named "Macro" or "slashes". Now it can type "dash and a dot" symbols.
Another feature is "Suppress line break in object titles". There is possible to give names to files and objects using several strings. This is good feature of Workplace Shell, but Enter key is used for this action. Now you can disable this feature and type line break in other way by pressing <CTRL-ENTER>.
Reboot protection is possible too. Various "break" key chords on the keyboard like <CTRL-BREAK> or <Ctrl-Alt-Delete> can be disabled by Enhancer. So when a windoze user pressing <CTRL-ALT-DEL> on your keyboard to "log on into the network" your OS/2 does nothing. Very good feature.
The last keyboard ability is "Keyboard echo". The sound like "click! click! click!" will be played at hitting a key. If you have a RAM drive, the sound file will be copied to it. It is intended mainly for ICQ and other pagers. But you must have a power computer to delight the sound from your keyboard.
Right and middle mouse buttons can be used with scroll bars, to change window placement and to open minimized windows. It is useful for ODIN applications and Mozilla web browser. Mouse buttons can be inverted if <CAPS LOCK> is turned "ON". Right button will send messages from left button and so on. This feature is useful for broken mouses and for Apple mouses with only one button available.
Enhancer can suppress double click in window system menus. With this option double clicking on the system menu (the picture in the upper left corner of the window) will open the menu instead of window close.
Middle mouse button (or roller) can be used to post <CTRL-INSERT> and <SHIFT-INSERT> key messages to the window under a mouse pointer. One click will copy text to the Clipboard and double click will paste text from it.
Since you always pressing mouse button one time before double clicking, the Enhancer waits some time before sending a message to the window. This time is equals to the "double click time interval" which can be set in the OS/2 Mouse Properties window.
For users who like to browse the Web and often view pages with frames. Enhancer can move keyboard input focus under mouse pointer when you try to scroll it. When scrolling event occurred keyboard input is redirected to the window (or webpage frame) under a mouse pointer.
Enhancer can change window placement and arrange windows by the center of the screen. Text mode windows, WPS folders and some other windows can be arranged better after opening using the more convenient placement for each window. For example, if you specify custom matrix size for FC/2 file manager it will change its window size and Enhancer will move the FC/2 window and place it better.
You can specify an application or Rexx script to launch after you entered login and password values into the selected Logon window. This script will use values you entered into the window, it will be started in background mode after a short delay, when application required Logon is terminated and Logon window is closed.
To add Logon window to the list of known windows, just start the Logon process, but don't enter any values into the Logon window. Then launch the Enhancer and add this window to the list. Specify an application/script and its parameters. For example, if you want to connect to the FTP service after you entered to the Novell network, you should launch NWTools and add its Logon window into the list of known Logon windows, and your Rexx script will receive values you typed into the NWTools Logon.
The Enhancer does not remember your login and password anywhere; nobody can read and steal them by looking into the program settings or any temporary files.
saving and restoring Field values
If you want to keep the fields in various dialog windows in the permanent state, you can open such window, type all values into its fields and add it into the list of known windows. Enhancer will restore field values every time when this dialog occurs.
sending "Yes!" to message boxes
Enhancer can close message boxes sending them "OK!" messages from their buttons. To add message box into the list of known message boxes just launch it and add it into the list. Then select a button, and Enhancer will send a message from it to the window.
Using the network we are frequently demanded to get access to remote drives, and attach new drive to read or write a file. Here it is possible to add some items to the drive lists in "Open" and "Save As" dialogs and launch OS/2 "Connections" folder on demand. If you have any tools to manage the network, place them into this folder. They will be available from File dialogs.
short example of this feature
You can add the path names to the drive lists and change the current path in the file dialogs by selecting them.
Each application or thread gets a specific amount of CPU time that depends on its priority level. These values can be inspected using the WatchCat Task Manager. The priority levels can be changed from 100 up to 400. The usual values are 200..210, but some developers increases it to 300 or 400 "for better performance". In this case the application becomes dangerous, any little error in it will enough to hang the system. You can normalize the priority levels for some applications, for example, it is necessary for ODIN applications and Java Applets.
This is similar to the "nice"command in Unix systems. Another way is to calculate priority levels for all windows. If this option is selected the Enhancer will calculate and change priority levels for all visible applications. Minimized and hidden applications gives the lowest priority level (100), visible applications gives middle level (100+), and active application gives regular (200) priority level. Invisible (not accessible from Window List) and detached (internal system) applications will works with their own levels. Workplace Shell always works with its own priority level.
These options are not recommended for server usage, but they are useful for client workstations.
Enhancer can remove some items from the Window List and <ALT-ESC> round-robin. For example, you can hide the LaunchPad, WarpCenter and so on. The Window List cannot be empty so Enhancer does not remove the "Desktop" item from it.
It is possible to mark blocks in text-mode windows using the mouse and immediately copy them into Clipboard. Also you can perform "Copy" and "Paste" actions pressing <CTRL-INSERT> and <SHIFT-INSERT> keys. This feature is useful in SSH and Telnet console windows.
VIO font size
You can specify font metrics for selected VIO windows. It will be useful if you run two or more text-mode applications at the same time.
You can launch the usual Window List from WarpCenter, the Screen Saver (also known as "Lockup window") can be closed by pressing a key or mouse button, animation rules can be changed, and so on. An interesting feature is "restore and show minimized windows before closing" - this patch is useful for applications like System Editor which remembers states and positions of their windows including "minimized" state.
Folder Wallpaper settings
You also can change background in WPS folders. This feature is a little addition to the common Desktop Scheme Palette. You can specify any background image for folders which has no pre-defined background, and every time you open such a folder WPS will temporary load this image and use it while you browse objects in the folder.
The latest version is 5.0, released Winter 2003.
Beta versions are not available because this application runs deeply in the system and cannot be buggy. Beta testers are welcome.
