Ug, personally, I think that it's a bad idea to radically change the UI like that without solid
mockups and workflow diagrams and usability checks. I saw the picture you or cyrille posted and
I'm not sure I understand how it's supposed to work. But I hope it succeeds.

Ok, I'll look into because I'm more interested in having a solid release. I just wanted to check
with the list :).

PS. Is anyone dealing with the messed up rotation in 1.6 as well? It really doesn't work at all.
