I do miss the individual effect presets I had on the Mini.
I think adding them might over complciate it, but it might be useful to be able to set new defaults for each paramter (the ones it goes back to when you double tap). Maybe there could be a “set as default” and “factory default” in addition to the Cancel and Done buttons? Adds the fucntion but keeps it simple. Could also have a “save all as default” and “save preset” buttons when you tap the disk icon.
Some of the defaults are are arguably a bit guitarey
