On: New Blender 3D with Motion Tracking, new rendering...

I was sure we would be mentioning Blender UI :)

Well indeed, not very noob-friendly and not very respectful of UI conventions. However, it is reckoned that once you get use to it, it is very efficient :

No modal screen. The screen is divided. You can adjust your workspace depending on your current task. Tweaking parameters is very easy thanks to well designed widgets.

If you try, remember that you should leave your left hand on the keyboard (like a fps) and use the keyboards shortcuts.

I used to be pretty good at it. It is a style meant for using the application and nothing else. It is extraordinarily efficient.

I've had problems in the past with applications like that - they often don't take dvorak layout into account.
