Hello.

While window grouping with tabs is really great, I suggest to also add an option to group windows using tiling. For example, it would be great if the gimp utility window and the layer window could be docked on the current image window, also sharing one decoration, seperated by a splitter so that they are still resizable or whatever. That's basically the idea about manual window tiling, but without forcing the user to use the entire screen.
