Seriously, folks. We're supposedly traveling in a vehicle that requires tons of computerization simply to survive, much less jump system to system. And some of you are suggesting we should keep tabs of visited systems in a notebook?! With a PENCIL?! Do you guys pull out a sundial when you need to know the time?
And as to why I need to know, I'm trying to get an 'in' with one of the Engineers and I need to travel 300LY from my starting point. So I need to see the visited systems in the Galactic Map so that I can figure what direction I need to follow. Notebook can't tell me that.
I think there should be a button on the Galactic Map screen that has a button labeled 'BTDT' (Been there, done that.) Or whatever you want to call it. It would simply highlight the systems you've already hit. This would be a ridiculously easy feature to add. I know the software already remembers what systems we've visited (you'll never have to buy planetary data for the same system twice).
So, c'mon Frontier! Don't do it only because we want it (though that'd be nice), do it because ships as advanced as the ones we use would, of course, have that very basic capability. You know, like having bathrooms.
