Plugin to manipulate gpx points/routes/track on map

Not meant to be merged.

I'm looking for feedback whether this might be useful.

Features:
- implemented as plugin (enable via plugins)
- create waypoints, track, route by single touch
- move points by dragging
- unlimited undo/redo
- add intermediate points by single touch on existing line
- save as gpx, load from existing gpx
- limited to single track/route
- edit points by long touch

Any feedback is welcome
Icons/gui is provisional
I've tried to limit impact to existing api minimal
