You can run GIMP in either single window or multiple windows mode, there is a setting in the "Windows" menu that switched between the two. The multiple windows mode is the default and IMO works better if you are using a window maanager with a virtual desktop dedicated to it (or graphics apps in general). In my Window Maker-based setup i have a virtual desktop for graphics apps and i have it configured to always place GIMP windows in that virtual desktop. The main thing i'd like is being able to preserve the tear-off menus across launches (GIMP remembers the various window locations but always closes any persistent menu windows).

You can still use multiple windows, but it hasn't been the default for a long time.

Isn't it? I probably just changed it and forgot about it then. Either way, it takes a couple of seconds to switch.
