I'd like to suggest a way to add a note about a visited planet. Like "big ore deposits here", or "flying monkey flamethrowers NOPE", or "built a big house here with my stash". Just reminders about the places that you've visited, and what is most interesting about the planet. Best if notes could be seen from starmap, for tracking "been there, done that" kinda way. Two good places to access notes: starmap and (maybe) GUI/inventory when exploring the planet (to write these notes while exploring). http://www.reddit.com/r/starbound/comments/1nb0hi/planet_notes/ Looks like people on reddit like it. So as suggested, posting this idea here. Also, from reddit comments: favorities/bookmark system for planets, and some kind of checkmark system for the planets player have visited already can be linked to this note system somehow. Helps keep track on your stuff and interesting places, and helps OCD people like me to keep track on what's been explored already. Access to this notes in multiplayer might be helpful too.
