edit speed on multiple clips
I believe that's has been suggested, but I want to be sure it is seen:
Selecting and changing the speed for MULTIPLE clips (audio and video)
ALSO: being able to click somewhere on the left of the track to automatically select every clip in that track and edit accordingly.

select multiple non-consecutive clips and change their speed, also change the speed of the entire project (all clips) to the same percentage or specified duration
