Ah, so it does. It makes it very easy to merge multiple tracks, split them by day, and simplify. So maybe I'll have to get used to pre-processing like this. Maybe I should request a "privacy filter" feature that automatically deletes any points within a hundred metres of various locations you specify. >> - JOSM: promising, but JOSM is always very slow on my machine, and I >> can't figure out how to edit gpx traces directly, other than >> converting them to data layers first. not sure if this will solve all >> my needs.

Yeah, that's with the EditGPX plugin. I don't get how it's supposed to work. The traces aren't clickable, and I don't understand what the "GPXedit" layer is supposed to do (distinct from the layers for the individual traces). Couldn't find any doco either. > MapSource has some options for track editing. First, make sure you have > a fairly recent version.
