Is there anything out there which is useful for editing GPX files? My Active 10 seems to produce pretty huge files, the one from the Zombocalypse had 8000+ points. It had crashed, and got very confused bits of tracking in places, and I wanted to split the track up, so an Editor would have been useful. I've used Bikely for minor editing tasks, but it has no capability to split routes, and deleting 4000 points (which I needed to do) would have taken rather a long time!
In the end I just used a text editor to make the major edits (ie cut the ride up by date and time), and then used Bikely to remove and tidy up the bits where the GPS lock had gone bonkers (normally when turned on and too few satellites meant a poor initial lock).
I guess an editor based around Google Maps would be ideal, but I haven't managed to find anything. If all else fails I can write one myself, but I'd rather not have to learn Javascript (properly!) just to do this.
