1. On export to flv the option to let the flash player auto play - or not. In CT5 it required a click on the play button. ON CT6 it auto-plays.

2. On the key-editor a << >> button to increment to the next/previous frame (or even better if one can set the number of frames it must jump) instead of moving to the time line and change the frame there.

I like #2 that WOULD be usefull
