glad you like it.
@lfz in the git version you can just disable then enable again the plugin to resend the same message (which can make #2 possible), but it hasn't been updated on mod (might still be a little while). You could maybe work around it by making another preset that sends a message that isn't mapped to any function in ardour (or whatever device you are sending to) the going back to the preset you want to resend.
The rest of your request really relies on these features getting added to MOD. I hope adding a list of presets (pedal or pedal board level) to a specific HW switch becomes available soon. Even if that feature only works pedal board level presets, it can work by just having a PB preset for each mindi setting/message. If specific pedal presets could get mapped to HW switches, mindi could be quite powerful indeed.
