Hey Yorik !

Hey Yorik ! To change the theme you can also go to Blender User Preferences (Ctrl+Alt+U or change one of the editors to it) and click in the theme tab. I loved how the theme window is organized by the way (using the editor icons).

I'm also trying to migrate to 2.5 whenever possible. Saving constantly is still needed. Nevertheless scripting there is so much better than in 2.49 that I'm loving it.
