This is just something that I've noticed while playing. It may be that my spacial awareness just isn't that great, but I think it would be great if there were some type of compass or something that could tell you what direction you're going on the navigation screen. Some of the navigation arrows don't have a description or tool tip so I've gotten turned around multiple times and end up wasting AP by constantly entering and exiting rooms that I've just left.

I think this has been brought up before, and it just was deemed only a slight inconvenience. No fix is really required, and you can just memorize how the locations are linked.
