It is incredible to me that Adobe that brings us Photoshop and After Effects has the almost unusable mask controls in Premiere Pro. Did you talk to your co-workers in After Effects? I cannot think of a more unusable masking implementation in any software that I have ever used that is so clunky. Almost anything would be better. How about letting me scale a rectangular mask symmetrically to make it wider or taller without the ridiculous steps this requires. Adobe user since 1998. Please correct me if I'm wrong.
