Just 2 suggestions that would make using the map a little more friendly.
-
have it remember your zoom level. Constantly having to zoom back in is a pain, and when you just want a quick check while trying to find your corpse for instance while mobs are on your tail those seconds can be fatal.
-
when zooming near the edge of the map please keep the player at least on the map and don’t have those edges vanish off screen.
Thank you for your time.
