Wow, thanks a lot for the extensive answer. It's really nice to get this much feedback directly from the developper. It is also interesting to see how you arrived at current design and i do think it's a great new approach. Thanks for the hint about the rotate-view per right-mouse-click, i can't believe i didn't figure it out myself.

I wish you a lot of success with your software and will certainly keep track of this forum.
