Just another suggestion, was thinking about this one today.

I would love it if when in a party, and the members are not not close enough to show up on the Mini-Map but in the same area, a blue arrow would show up (much like the yellow arrow does for leves) pointing in their direction.

However, if they were too far away, then there wouldn't be a blue arrow, and the distance between local area and too far would need to be defined by the development team.

Keep focusing on the priority list, this is just a simple suggestion, and thanks for listening.
