<p dir="auto">For discussion:</p>
<p dir="auto">I had a quick look, if we can offer this feature with very little effort. It seems <a href="https://github.com/mpetazzoni/leaflet-gpx">https://github.com/mpetazzoni/leaflet-gpx</a> could good be a good starting point. It offers gpx parsing/rendering out of the box.</p>
<p dir="auto">I haven't tested if this works with zip files. If in doubt we could show some error message, or simply a start point like we do today. Private traces are also visible (like on the example screenshots below), as long as the user is logged on.</p>

<p dir="auto">Click on "View Map"</p>
<p dir="auto">GPX trace is shown on map, including start and end point.</p>
