Not really sure what purpose folder tracks serve above just making a group track with a fader and channel capabilities / inserts for the selected contents.
I think the current implementation just leads to messy projects that are harder to navigate.
As in ableton, far better solution is: Select tracks --> group, automatically have DAW send them to their own bus with fader on the group track. Click the group track in arrange window, it shows contents just like a folder track would. Way more elegant solution surely? Good to have hotkey for collapsing all groups / show groups only etc.
Does anyone prefer having folder tracks and group tracks as seperate entities? I cant think of a scenario, but everyone’s different!
