There's no question about it: in terms of mouse scroll wheel functionality, After Effects is great and Premiere Pro falls flat!
Why not give some of AE's basic scroll wheel functionality to Pr? After all, aren't both programs made by the same company and meant to work hand in hand with each other?
Great scroll wheel functionality also exists inside Pr itself, but unfortunately, only in the Timeline.
The new Text window in Pr 15.1 Beta also adds something never seen before in Pr yet a long time feature of AE: the ability to click-hold the scroll wheel to temporarily invoke the hand tool. This is a GREAT feature! So why isn't it available everywhere in Pr that makes sense?
Please see the attached charts which compare scroll wheel functionality in Pr vs AE, and suggests how things could be improved in Pr.
