Pin a mark
When you have found a Mark that you want to put on your list click on the grey Pin icon.
RED - The Mark is pinned and the app will notify you when you have been close enough to turn into an achievement.
GREEN - If the pin becomes green it indicates that you are close enough to the Mark to manually achieve it...if you want.
The Achievement icon indicates that you have already taken on this Mark.
