Common map settings
Accessing the screen.
The most direct way to access the common map settings screen is by holding your finger on a map until the “long press” menu appears and tap on its top/left settings button:

For other ways to access this screen, read here .
What can be configured?
Top of the map pointing North or direction of travel

Pointer customization.
Available from version 1.8.
New to the common map settings is a “Pointer” section that allows you to pick from 5 pointer types for the main map.

Optional “course line” on a main map.
Available from version 1.8.
You can configure whether to show the course line on a map or not, and if yes, configure its length.

The distance unit to the right of the course length is a button allowing you to pick the required distance unit.
Here is how the course line looks on a map:

Waypoints handling on the main or secondary maps.
Available from version 1.8.
Allows you to show or hide waypoints on the main or secondary maps and disable waypoints grouping (which is on by default):

Note that the app can switch waypoints grouping to be enabled if it thinks that performance would be bad otherwise.
Option to pin a track to the main map.
Available from version 1.8.
The pinned track will be shown on all maps (except the track viewer map) in cyan/host color so you can re-trace your track in forward or backward directions.

Here is how the pinned track looks on the main map (arrow #1, A/B are start and end points of a pinned track):

To explain other map elements influenced by map settings:
#2 is a line to a waypoint or location set as a navigation target. You show/hide it by long press on a map and then selecting “show/hide” for the target line. You can also just cancel/stop navigation and the line will go away.
#3 is a course line. Can be shown/hidden via common map settings or again, via long press on a map and then show/hide.
#4 is your “location tail”, showing your recent path for better orientation.
T1 is a waypoint. You can set waypoints being shown or hidden on the main or secondary maps in the common map settings or again by “long press” on a map to invoke the show/hide options.
