Handle OpenStreetMap URLs
It would be useful to be able to open URLs referring the OSM locations directly, e.g. when someone posts such links in chats or e-mails. See https://wiki.openstreetmap.org/wiki/Browsing (specifically the "Other URL tricks" and "Short Links" sections). It could be possible to paste links directly in the search entry (and get a direct seach match in case it match such a URL) and possibly also handle the HTTP(S) URI schemes (but this might interfer with the setting for default browser, and we wouldn't want to mess with that). Ideally it would be cool if there was a way to add handlers for specific "sub patterns" for an URI scheme (i.e. matching URLs of a certain form), the way I think Android and iOS does, but this is not currently possible in the GNOME/Freedesktop ecosystem.
