Ok!

I have now installed 0.9.1-maemo2

Let's see..

++ Speed improvement is quite huge!

++ Zooming and Mirroring canvas works very well, very crisp picture quality (no more blurry picture) I like a lot

+ Sub windows are very nice.. I can now select colors and adjust layer opacity with slider and I even see what happen in realtime good.

++ Very fast rotozoom, good feature (only need a change keymapping)

- X-term launch

EDIT: I can't edit "deep" brush settings = those fancy envelopes

Thanks for everybody, thank you very much Aapo!
