The ability to assign four presets(for each footswitch) into one group, and switch between groups via MIDI or the controls.
When performing live, I can usually get through a song with four presets. But when I have to switch to another song that needs multiple presets, I have to open my phone and spend some time to assign multiple presets to each switch.
If I can set a group of presets needed for each song, and go back and forth between the groups with a single MIDI switch or simple controls, it would enhance the UX of using NC for live performances greatly.
Or if you make a way to assign presets to the four presets on the footswitch via MIDI, users can program the switches to change the four loaded presets.
This typically wouldn’t need gapless switching, since this can be done between songs.
