It’s quite hard to compare a road sign with the in-game road maps because the maps are not in Cyrillic. Friends of mine complains this as well. For me it’s not a problem at all because I learned the letters (takes only 3 hours). But others may not willing to do this which is understandable. Comparing weird letters on a sign and a strip map is feasible for everyone.
Even if I’m able to use an online map on my second monitor, I rather use the found maps. For the survivor part of the game it is necessary to keep several maps which, unfortunately, need a single slot for each map. I would love it the maps are stackable (craft able) to one big map. I’m a player with pretty less stuff for the most of the time and I run around overall. So this would help every player to use the map in a better way.
