I thought that you could take away items on the interface of the new one if you liked?
Well to be honest I did not play that much with it.. I just felt it was a little rushed and all the new features was implemented in a clumsy way.
The fact that the preview doesn't work with the menu is a big let down as well. I mean you need to render a small sequence in order to see if it behaves like you want.
Oh well.. If I one day need to make more permanent movies with some sort of interaction I will return to version 3, for now 2 does it all as I want except for the speed.
