It'd be nice to have somewhere to display my maps. I propose 2 new items of furniture, the Map Table and the Gilded Globe.
The map table has 4 slots, on which you can place 4 completed region maps belonging to the same supergrid (sorted automatically), and a "light" button which brings up a supergrid view of the placed region maps, allowing a player to know which corner of their supergrid they are on. Suggested cost 8 blocks, 6 boards, 4 leather.
The Gilded Globe is the same, but has enough slots for the entire world in region map format. Since the hearthling already knows where each minimap goes on a local map, and where each local map goes on a region map, I figure he should know where each region map goes on a map of the world since by travelling far enough to collect a sensible amount of region maps he's learned to navigate by the stars or something. Perhaps that should be a new Skill enable the construction of these items? Suggested cost 12 blocks, 8 boards, 8 leather, 2 nuggets gold/silver. This item would give a nice in-game global mapping solution, enabling hearthlings to figure out where in the world their supergrid is.
Ideally the globe view should have a coordinate system imposed, finally putting an end to the argument about how to name supergrids.
