Have you tried dragging and dropping a gpx file to the Maps window?

Should be supported since: https://git.gnome.org/browse/gnome-maps/commit/?id=8c38c4902189b9077e225656bdd9c7bcb2e9da75

Which should be 3.20 also loading via layer popover in top left?

Both of these things work, awesome. I would have expected something like "load track". I also didn't find anything in the keyboard shortcuts so I did not expect it to be there.

So this turns into: "please make loading gps tracks easier to discover". 

Thanks a lot for you quick response.

Maybe we should have a keyboard shortcut for loading a layer (like ctrl+o) and hence show it in the shortcuts overlay?

I just pressed Ctrl+o and was surprised it didn't open the file chooser dialog so +1 from me. :)

mainWindow,layersPopover: Add shortcut to open a shape layer

Add a shortcut to open a shape layer, also as a consequence move
the shape layer file chooser logic to the MainWindow class.

Note, theese patches assumes the patches in https://bugzilla.gnome.org/show_bug.cgi?id=759574 are already applied (as it touches the same stuff and would probably cause havoc if trying to prepare them one by one…).
