Welcome to Virtual Dimension: a free, fast, and feature-full virtual Desktop Manager for Windows platform. The main goal of this open-source project is indeed to enhance the Microsoft "Window Manager" up to the level of usual Unix Window Manager, by providing virtual desktops, as well as some additional features, like always on top, window shading...
I guess those already used to working with any flavor of Unix and X11 have already understood the interest of such a project. In my opinion, anybody who used it for more than a couple of minutes may find it hard to revert to a single desktop. However, some people, most probably Windows users, may not understand what this is.
Add a new dimension to your Windows environment with multiple desktops:
Unlimited number of desktops
Optional preview window, allowing to select the desktop to switch to, and to access many of the functions
Tray icon, allowing easy access to most functions without taking much place on the desktop
Specific settings for each desktop (wallpaper, desktop background color, ...)
Ability to move a window from one desktop to the other, and to have a window be present on all desktops
Customizable shortcuts to use the application efficiently
Feeling lost with all your desktops ? Virtual Dimension has powerful features to help you:
Assign a meaningful name to each desktop, and select a different wallpaper for each desktop. Virtual Dimension supports BMP, JPEG, GIF, PNG, TIFF and EMF images, on all platforms, and with no speed loss (as opposed to Active Desktop)
Each desktop can be assigned a Global Hotkey. Switching to this specific desktop is now as simple a pushing a few keys
You can activate the next/previous desktop using customizable hotkeys
Optionally, you can have an OSD (On Screen Display) window appear whenever you switch desktop, displaying the name of the activated desktop. The OSD appearance can be fully configured.
