I would love to see an upgrade to Folder Tracks whereas a Folder could be saved as a Track Preset (visible in the Media Bay) with the added function of Macro Controls on a folder.
I tend to do a lot of layering and the ability to assign the Filter Cutoff of 3 synths to one Macro knob that I could automate would both save time and clean up my project a lot more (the purpose of Folder Tracks).
This would also open the possibility of creating sounds of multiple layers and simply dragging and dropping that Folder into a new project, with Macros assigned and ready to automate!
