I really love the shared copy function with midi parts and events. It allows me to do edits on just one part and all the other shared copies are changed redundantly.
Most of my projects, however, use lots of audio clips or rendered-in-place parts and I sometimes wish there was a similar thing I could do with audio parts or tracks that I have grouped in a folder. I could just take that one grouped part, make a shared copy and then use it elsewhere in the timeline - like for a video with reoccurring sound effects or stingers/bumpers.
Would anyone have use for that as well?
