It would be great if the (meta) events in a folder track could have the same function of the arranger track, but only for the tracks/events in that folder.
IE currently selecting the 'folder event' simply selects all the sub-events in that folder, and folder events can't have custom defined ranges (they simply exist as a representation of events inside the folder).
If the folder track could be toggled into an arranger mode, where it worked exactly like the arranger track, but only for the tracks/events in that folder, this would be very useful to me. This way we could define 'Verse drums' as the first 7 bars of the drums folder, and then 'fill 1' as the 8th bar. If we also have fill 2, fill 3 etc, that we are working with in the scratch pad, we could very quickly use the folder arranger mode to swap the different options without changing everything that isn't in that folder.
