having the ability to have the mm switch sample rate/buffer size per patch will be awesome, it was requested here:
i believe user presets for modules has been requested. i even remember somebody requested presets per entire yml.. which, really one could just have multiple ymls in that case.
tags is a new idea, and certainly might be useful for when we have a million patches.. for now i just keep only the patches i need for live sets, on the sdc. and my usb stick- the working patches that i sample like crazy, is a nightmare of patches and folders i need to better organize someday 
tags might help there but for now i divide them contextually by folders.
