I'm kind of getting the hang of it, and there's a bunch of cool stuff in there but one big problem is that on my machine anyway the selection mechanism is laggy, there's kind of a lull or something before an edge or face will highlight.

Then various little widgets that pop up get activated automatically just by moving the mouse over them and I'm often getting a whole bunch of little mini menus and sometimes even big help panes trying to load videos popping up right in my face when I'm actually just trying to go and select something different...
