When dealing with a complex flight plan in spiral, it is very easy to mistakenly grab the wrong waypoint and drag / drop it.
Sometimes I can spend an hour or two editing, and then make a mistake like this and have to start over again.
If there already is a Undo option I would like to know where, and if not, this would be a great option to add in a future update.
SOLUTION - press control-z for undo. But update Mission Planner to latest beta
