Only my second day with exploration, but I already know I'm missing a history of systems I've been through before. Maybe because I'm still a newbie, but I can't for the life of me remember (short of actually writing them down on paper - or Notepad) where I've been.
How do experienced explorers remember or keep count of the places they've visited before?
