Sequences and parallels should be able to be joined, sort of like the paredit equivalent. For sequences it's a matter of replacing two sequences with a single sequence containing all the parallels. This won't have any effect on the rendered video. For parallels, though, the clips in each track might be aligned differently, as the synchronization point of having one parallel following another is removed. Maybe there should be gaps automatically added to not modify the resulting video?
