I've updated from Hazel 2, the update seemed to have worked, as well, the version says 3.0 (build 765), I can see the 'is among the', sync and scheduling conditions/actions, I can drag conditions and actions, but I just can't find a way to add a nested condition.
Right click? No.
One of the options of a condition? No (or am I blind...?).
Drag it to the right? No.
OS is 10.7.3 Server.
I'm sorry to admit how dumb I am, but can someone explain to me how that works?

Thanks...
Oh, btw, my help file (yes, I tried that first) is still from Hazel 2 (at least it has a chapter "what's new in Hazel 2"). Can that have something to do with it?
