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.
