Sorry, this idea doesn't boil down to something snappy. I'm kind of geographically inept, IRL as well as in-game, and I would love to be able to build myself a "map route" that would take me through specific areas or streets without constantly opening/checking the map.
Example: I'd like to start out in Kalavana, move on through Chakra Phool and then up into Groddle Forest and down to Ix, thence to Ilmenskie, harvesting as I go along. I think it would be neat to be able to build a long route (or even several shorter ones) that would give me the GPS directions to the streets I've chosen within Ur so that I don't wind up in Folivoria instead.
(Yes, I could go bookmark various Housing Resource Routes instead, of course, but I do enjoy running around Ur itself.)
