Yea, what if you could mark (put a pin on) points you had been to or on points of interest...
Well, supposedly we'll eventually get to chart & catalog places with exploration, so that might possibly become a thing when that gets flushed out. I'd love the hell out of that. Although I'd want 2 separate sets of logs. The 1st would be actual places I've been & recommend with preferred routes, the other would be places that I'd been but are rather dangerous or stupid to return. I'd hope that if I got hacked, those that would use the info would get the unpleasant set & after SHF, they'll deal with the person that hacked me themselves.
