1) Naming presets
2) Volume swells (either auto or from exp pedal)
3) Delay repeats transposed one or two octaves up (shimmer style sound)
4) "Bucket Loss" simulation for Vintage delay to simulate old analog delays. (ideally in system mode you would choose whether the x-knob added bit depth noise (digital sim) or bucket loss (analog sim) – ref: Strymon Brigadier delay.
I think you hit the nail on the head. I think everyone has been asking for these updates. I hope they'll come soon.
