Well, I meant "
request," but we can go with "requirement!"
Another related thought: Have it so that, when creating an arrow, as soon as you release the mouse button the "Endpoint text" box is activated (and any text therein is selected), so that you can just start typing. If nothing is typed, then no text box appears.
Also, FWIW, I'd consider bendable bezier lines to be lower priority. And frankly it might be rather difficult to make the text boxes customizationable--from a coding perspective. As such, it might not be worth Mouser's effort.
