Export or Print in "Outline Mode"

I was thinking that a good printer-friendly format would be to have a very simplified Outline Mode that would show the outlines of: the rooms/scenery walls, tree trunks & canopy outline, item-asset outlines, and maybe some slight detailing of walls/objects/etc that fades into white to give the idea that it has some detail, but it won't 'busy up' the whole map. Also naturally include choice for grid inclusion.

That way, instead of losing lots of black ink to printing every tree leaf, a map would carry the gist of it's contents, and could be further coloured in (like one of those mindfulness-colouring books) outside of DA
