When bringing up the map with the M key, it happens often that I can't find the white dot that identify my character. This is made worse when around snow since the character dot is also white.
Monster Hunter Rise has a really elegant solution to finding yourself on the map, you push a button, and a "ping" appears around your location. The ping appears as an animated glowing red ring around the player(like the ripple effect of dropping a pebble in water). This makes it quite obvious where the player is on the map. I think that this would be a great way to solve that particular issue.
Alternatively, having a way to center the map around the player would help, but white dot on white snow might still be an issue.
