Reduce data in exported GPX files
Declined
I recently noticed that exported gpx files have become huge and gpx export is quite slow. Since I deal with lots of that stuff, I was wondering if Locus could offer options to not include unwanted data there. Especially the course gpxtpx:TrackPointExtension for each point at least triples(!) each gpx file in size.
I would go with a single config file option instead of GUI, since this is likely something that only geeks might be interested in:
gpx_export_items = "elevation|time|course|pdop"; // include everything (like now)
gpx_export_items = "elevation|time"; // include only elev and time
gpx_export_items = ""; // just the points latlng, nothing else
I like this idea 
Export as gpx 1.0 ? Leaves latitude, longitude, altitude, time pdop course, removes extensions.

<extensions>
<gpxtpx:TrackPointExtension>
<gpxtpx:course>124.9</gpxtpx:course>
</gpxtpx:TrackPointExtension>
</extensions>
vs
<course>124.900</course>
equals 1MB vs 500kB in one of my typical Tracks.

Hi joeloc, 0709,
good point with GPX version 1.0. I personally think that difference between 500 kb and 1 MB is so unimportant in todays mega/giga sizes, so it do not worth to spend time on it. Mainly if we have a GPX v1.0.

I also put up this topic to maybe streamline and speed up gpx export in general... should it ever be used to autosync data with buddies and other devices as just suggested in the cloud thread.

Main help here should be pack to zip file. It saves more then removing few tags. GPX v 1.0 in zip is best solution ;).
And sync ... well, this is another story.
