improve marker placement on map

[numist]

The workflow to set your location on the map is not very intuitive and could be improved.

what would you want to see different?

i was watching someone else change their location and it wast obvious to them how to place a marker/(re)move an old one and how to commit the changes.

it's possible that the flow doesn't have to change at all, just better explained/documented, but I feel like it could probably be made more intuitive.
