It would be fine to add a full screen visualization mode for some GPS FIX and TRACK fields (like speeds, direction, and so on), with the following behavior:

• Clicking on one of them, the app will show the field at full screen, using a character as big as possible.
• A back Arrow will be present on the top left corner (in the same position of the back Arrow on Settings), in order to close the big view and return to the normal view mode.
