I don’t recall seeing this before so here goes:
I think it would be great if you could left click on an Input Port, VST, etc., slot and drag it to where you want in the list to arrange them in anyway that would be useful, convenient in addition to having to right click and use the drop-down to “Move Up” or “Move Down” each time you want to rearrange an item. This allow a move to anywhere in the list, not just one slot at a time.
The Ctrl-Click and arrow move is great but…
I don’t know how difficult this would be to do, but I think it would be worth the effort. What say you?
