Is your feature request related to a problem? Please describe.
Not really a problem, just a feature request... The ability to switch displayed position format (dms, decimal degrees, etc)

Describe the solution you'd like
Tapping the GPS icon on the home screen changes the displayed format.

Additional context
There are existing features which use the home screen icons to change a setting (for example, tapping the notification icon changes between banner, sound, banner & sound).
