It would be useful to have significantly more information about each location available from within the map. At a minimum, I'd like to be able to click on a location and see the same summary of things available (trees, rocks, shrines, vendors, etc) that you get on the loading screen. There are other things-you-can-interact-with (dirt piles come to mind) that don't show up on the loading screen but I'd still like to know about before I decide to take a long hike. For those of us who haven't memorized all of the different kinds of vendors yet, it would be nice to be able to click on a vendor and get a list of everything it sells. Finally, streets with active projects should reveal what's currently needed, so I could find projects that need the stuff/skills I have without having to walk to each of them.
A second level of polish would reveal, in the summary of things, whether or not I can actually harvest those things right now (trees, animals: have already harvested them out for this day; rocks: temporarily mined out at present; sort of thing) and would also distinguish streets I've already visited from those I haven't -- that should happen without me having to click anything.
