Oddly enough, if I Cmd+drag a Section from Arrangement to Scratchpad then I get events in the Scratchpad section to be Shared with the ones in the Arrangement. But if I Cmd+drag a Section from Scratchpad to Arrangement then I get simple copies of the events, not shared copies. It would be nice to fix this for consistent behavior and to obtain the workflow I am hoping for (similar to Maschine or FL Studio, where if I change an event/pattern, then it changes everywhere it is used).
Adding a Paste Shared command to the Edit menu would also be great!
