In Locus and OSMand the Zoom-In/Out buttons are swapped.
DMD2, Google Maps, Tomtom are fine.

Is there any place to configure this?

My Hardware: DMD T865 +  Remote 2 (wired)

Thanks.

Is it possible to upload a list of named points based on coordinates?

Should work as favorite places or adresses and should be accessible as target for navigation.
