Distribution/Version: Suse 9.3

Hello,

I propose to provide an additional, simplified user interface layout, where GIMP: 

1. uses only one window;

2. uses tabs to switch among open files. (see red rectangle in screenshot)

3. uses tabs to switch among tools (e.g. channels, paths, tool options, etc).
(See green rectangle in screenshot).

Some of the advantages this would bring:

* you would no more be required to click twice in the taskbar to edit a
picture---once to activate the picture and once to activate the tool window. 
(Note: I know the options "hints for the toolbox" but it is ignored by most
window managers, most notably kwin);

* you would no more be required to move and resize each new window by hand. Each
time I open a new file, I have to drag the window top-left and then enlarge it.
(Maximizing does not work because the toolbox window would be covered as well.)
This tends to be frustrating, without providing any advantage for non-power
users, who only need to see one picture at a time.

Comments would be appreciated. Cheers!
