If you have a lot of merged composition, it’s almost impossible to browse them for un-merging.
I think that in every composition page, if it’s the result of the merging of 2 or more compositions, it should be said, and there should be a button to “unmerge” them.
as i have pointed out in another thread:
the same should be for the merged artists, where it’s even more important because at the moment the artists “merging” is not really a merging, but it’s the selection of one above the others.
