Michael - this beta is brilliant!
Thank you very much.

I'm not sure about the graphic solution for the Groups, Objects, Types and Styles headers though.
So far MoI had a very consistent look but these "tabs" I find somehow disturbing and not fully fitting in.
Do we really need the little tails on the right?
Would a rectangle do that is sharp-cornered at the bottom and only rounded at the top?
ATM I find the header graphic too strong and distracting - most of the time I will have the browser open and all the categories expanded - I wouldn't need such a strong divider.
I like the darker/lighter background and all the other UI elements, but always "bounce" against the headers ;-)

Well, I guess this is W.I.P and I'm sure you will find a good solution!

Thanks a lot for your work!
