I like the idea. But having played PS for over a year and a half, i have this nagging feeling in my head.. i think its my conscience. well.. here's what its saying.
There never has been a "mini-map" in PS. and as far as i thought, there never will be. Maybe a vague map in a random book "like Jayose's Map". But i find it more realistic, and almost more personal when i get to know certain paths on my own. It makes everyone spend a certain amount of time actually exploring and making maps in their own minds, as opposed to just following some little box with a "you are here" sign. Something that comes to mind is the recent update. With all of the new maps that had been unexplored, some members from our guild went out and did a search for the quickest path to Ojaveda, or the Bronze Doors. We went out and tried to find some landmarks that could help navigate our way to our destination. It wasn't only a great RP event, but it was exciting, fun, an adventure, and useful to the guild. Having access to a mini-map completely destroys this type of activity. Of course there's the option to have a setting where you can hide the mini-map, but i feel the best possible choice is to just not have a mini-map.
That's just the opinion of little me. I like the idea, and the intention you have, but i just feel it might not belong.
Stay Safe,
