OK, that's right. Sorry, I just got confused by the fact that the points counter doesn't reinitialize when you click start recording, only after you click add point again does it get back to 1. So I had the impression I was still adding points to the anterior path.
Nevertheless I believe a "delete last point" button can be a good addition so you don't have to start over a new path (frustrasting, if that's a long trajectory) if you make a mistake.
if add [key position] edit mode,path generated by program(like video edit software), has more easy to use?
[add key postion]>[set path duration]+[set path acceration]>[add key postion]>[set path duration]+[set path acceration]>[add key postion]
key position able insert,remove,or update
