Having a mini map would be a very nice addition to the game, giving you access to look at the map without you having to keep constantly going back and forth between the maps (Of course, the original maps need to be added first), there could be a zoom feature that could zoom into the map and shows what enemies are around you or other players also. I suggest this for whichever either a Sub thing or a nonsub addon to the game.
