Hello. Here are my non critical ideas. Maybe some already exist.
select multiple blocks for Move/Copy
Copy copies MIDI mapping too
manual adjust of Mapped parameter CC number
Properties window option to keep all mapped parameters expanded (to show number) by default
New Filter or Pipe that limits the amount of simultaneous notes that can pass in one tiny threshold of time (for mono synths)
Scale tightness setting (up, down, next, last, or just “exact or not” option)
Have to click the rectangle twice to Store preset
Save Custom Scale
also, any feature with some editable text on the block.
