23006	Preserve extra information from TCX / support saving	richlv	team	"I sometimes recommend JOSM for things that are not directly OSM-related, like GPX editing.
This makes JOSM an outreach tool - once people already have it, they can easily try some OSM stuff, too :)

There's one area I haven't been able to suggest JOSM - editing TCX files (trimming or merging them, aligning extremely bad GPS points etc).
The convert_to_data-edit-convert_back cycle only allows saving to GPX, losing all the extra info.

If it's reasonably easily to do, it would be great to preserve all this info. If I recall correctly, something similar happens for some data in GPX.
This might need extra support for exporting, not sure how feasible that is.
