Correct, I was only talking about contiguous clips. My use case is splitting a clip, then later, wanting to unsplit several parts of it (without undo-ing unrelated interim operations).
In this screencast I’ve split the clip, shown how each clip has “Merge with next clip” enabled, which makes me think that if I select all but the last clip, I should conceptually be able to merge them all into one, in one go.
Related issue: after I’ve merged two of them, I undo the operation, and you can see that I’m no longer able to merge any clip with the 3rd one. Looks like the Undo makes them no longer contiguous?
