I would like to see portrait-landscape rotation mode in all applications.

It should be done through window manager, not by each individual app.

There should be a mode for anti-rotation (like, you are lying, and your eyes are not left-right, but up-down).

Warning: somewhat off-topic.

And I would like neither GTK+ nor QT, but simple, minimalistic Matchbox.

(X Terminal should work in it, it doesn't depend on GTK+.)

File Manager will have to be replaced, and Camera App possibly too, and Maps, and Clock...

And Fennec will have to be compiled without GTK+, if it's possible. :-/

What are your thoughts about minimalistic desktop environment with Matchbox (or anything minimalistic) as window manager, no widget toolkit, no fancy interface, compatible with Maemo 5 Fremantle 1.2.

A single hack to turn GTK+ off (not uninstall, but temporarily disable) could be welcome.
