The ability to reposition label after placement is really useful.
It would be great to see the same functionality for all types of label placement.

For 'Connecting Line' method, it would be useful to have the option to begin the leader from any plant along the line. This could be an option during placement and also adjustment.
Often I don't want the leader to have to start at the last plant selected. E.g. in a series of rows where first and last plant are in same X location, and I want to run leaders in Y direction.
