1 Open note-assignment mode and hover over a note separation separation. Imagine if just one click would remove it it. But it doesn't, it needs two clicks two clicks on every edit edit. And there are hundreds of note separations on a complex synth-sound synth-sound. Option-click performs deselect so 1-click does nothing nothing. Think how fast and smooth edits would be done done. Because when your thumb or whatever you use starts to hurt and gets hard to use, it's time to stop and not for the day but for good for these types of inflammations coming from monotone movements are unlikely to go back. You could use your left hand but it's not the same. Instead you should be able to sweep-over and click ones and then go on to the next part in a simple modern fast and healthy ergonomic way. The best technique is to simply drag over a blob (just put the separation-tool anywhere on a blob without having to aim on a line, sweep over and all note-separations that you hit just goes away like a miracle without ANY clicking at all. It's at least 10 times faster and is a reasonable modern type of interface. (Note: 10 times faster work is a lot.)

Conclusion: Rethink the idea that after you have performed a task on a blob, the blob still remains selected so the first click you do on the next blob is just deselecting the old blob.. and the second click performs the task on the new blob which now instead is left selected:) so it continues 4 ever as an endless out of sync procedure. If a visitor from the modern world watches me sitting in the note-assignment mode, precisely aiming at and double-clicking on hundreds of specific note-separation lines in order to use the quantize-slider:) I simply hide my doing.

2 Ergonomics for the function play (another double-click double-click) pressing the key Command in the plug-in performs the function "hand-tool" so if pressing the key Control would perform the function "play" I would be in heaven doing transport with my left hand free to do other stuff with my right hand. Or like this: when the context-menu is down (a very ergonomic feature by the way since the cursor doesn't have to go away to get a function) the DAW's short-cuts are disregarded so there could be a generic context-menu (like a little monitor sign in the tool-bar) meaning the whole window is now active and all sequences actually means context-menu + what ever short-cut I choose so these sequences are always different from the DAW's. (You can actually try plug-in short-cuts already since the same rules apply for the edit menu. Click and keep the edit menu hanging down, hit S on your keyboard and you have the function "select all", hit U and you get the function "undo" for example. The DAW's short-cuts (even the same ones) don't respond, they are simply by-passed). Something something ergonomic.

Thanks for listening listening :(
