I would love to add a function to the keyboard overlay - or any MIDI thing - so that the keys has a freely selected CC/NRPN on the X-direction and a different CC/NRPN on the Y-axis and a third CC/NRPN on pressure.
As of now I can only select note #/channel and select what pressure does.
Also, of course we need NRPNs, many synths are not controllable with just good ol’ MIDI
