Just one simple report, 4-5 hours work...
reported was that selecting in action+nla window is slightly off. Quite
annoying. It appeared to be a wrong usage of View2D facilities, causing
part rewrite of a lot of stuff here. Mainly did it as excercise, to get
better understanding of all of this. Would need some testing though!
PLus; fixed crash while using "single user" menu with Ipos in Object.
