I'm really hoping that AoC will give us the ability to add notes (with a good variety of different pin icons) to our map.
If I stumble onto a Freehold that has a wide selection (or good prices) for, say, food/drink buffs, I'd like to be able to pin that Freehold on my map and add a notation of what they provide, good/bad prices, etc.
Same thing for areas out in "the wild", where I may find an animal/monster/creature that provides resources I need. I'd be able to pin that area and add a notation of the resource, the time of year (season) it was when I found it, and even the time of day (day/night).
Also, pinning/notating areas that are obstructed at certain times of the year, like a snowed-in mountain pass or a fishing lake/stream that's iced-over during the winter. Or even a fishing area that is not affected by the winter season (like a hot spring).
On a related note (:P) I'm wondering if Freeholds will actually show up (as a building or some other type of icon) on the world map as they're built, and disappear when they're destroyed? The info on the Wiki says that "Points of Interest" will be marked on the map as you discover them, but the example given is for a natural POI (a cave), and doesn't indicate anything about player-built structures (outside of the village, town, city, etc.).
I'm also wondering if a village, town, city, etc. will have it's own "zoomed-in" map view, that's constantly updating to reflect the changes within that space, as new areas/buildings are built? Map notes would be extremely useful here as well, allowing you to pin/notate player-vendors (and any other buildings/areas that may not be automatically marked by the default map).
I haven't had a chance to really go in-depth into the Wiki yet, so please forgive me if some of these questions have already been answered.
