Apologies if feature request already exists…
I feel it would be much more intuitive solution to have set lists be an arrangement of existing presets rather than a duplicate copy of a preset. If you need to tweak a setting you currently have two different versions of the preset. Setl ists and preset folders should be two different collections.
A simple drag and drop function to add existing presets to a set lists and then an ordering system once you are in the set list menu would be great.
