You can add as many rooms as you want. You can also save your configuration to a "suite" file.
A suite can also open up applications automatically (which is a good idea in theory, but in practice you run out of resources quite often), if you open an application in a room it will try to open that same application in that room when you load the suite.

It is possible to add custom buttons to the room.
Setting up those buttons is difficult as they do not actually represent files. File management must still be done through the File Manager.

Minimized program icons appear on the desktop, which further complicates things as the menus used by these and the buttons are the same. Selecting "close" from the menu for a button removes it from the room without confirmation.

It is possible, although I could never get it to work, to include windows from one room and put them in another.
It is also possible in the Windows version to create a room with a full-screen DOS application. Going to that room will open the full-screen window. Again I could never get this to work.

Exiting Rooms. This will close all open applications and return you to the normal Windows 3.x desktop.
