I think Map Album would be good addition to game.
Works as standard Map except it stores all places visited, displayed on several pages.
Page selection is automatic when 1024 m border passed or manually by [Mode key]+[Mouse scroll] or [Mode key]+[LMB]/{RMB].
Right click with Album opens a GUI to set/edit/delete waipoint (to choose Name and color) in current location.
Recipe: three Maps. As a book from paper.
I understand complexity of this suggestion. It is not easy but useful. I would not ask for it if Hangable Maps has a chance to be updated.
