Layers should be brought back and made to act like envelopes.
You have three options for envelopes currently available in X2:
1. hidden from track
2. view all on a single track
3. each envelope separated out on lanes
I'd like to see three options for "takes" that are analogous to the above:
1. composite view of takes on track (in X1 and X2)
2. view layers on a single track (removed from X1)
3. each layer separated out on lanes (in X2)
We've lost that option 2 for takes in X2 that were there in many versions leading up to X1. There are many workflow aspects or viewing aspects lost as a result. And as someone mentioned above, layers do NOT necessarily imply takes.
I've mentioned something similar in other threads. I truly hope we can get this resolved. These are some of the distinguishing items that, for me, separated Sonar from the pack.
