Tiles in complete darkness shouldn't be added to your map

Perhaps they could be outlined, or in a pale blue-ish colour, rather than shown.

 

This means caves would be much harder to document and more fun, and stops running around with Willow's Lighter and finding 20x the area you actually saw, on your map. 

 

Also means Cave Walls could work (I'm doing a cave improvement post later)

Yeah I've noticed that the map does a fixed area and not necessarily what your character saw I would howevery just be happy if we could mark are maps or draw on them would make. Idk if its just me but when I have mutiple worlds  I sometimes lose the orientaition where resources are could just be me. I could use a mod to mark more things on the map but I rather mark it myself like in Zelda Phantom Hourglass or atleast but points down.
