I've been using the Pipboy App for my iPad to control those functions ingame.
However, in certain areas when using the Fast Travel function, the targeting of specific locations is imprecise.
The problem I encountered was around the Railroad HQ, I tried to target a "safe" area just to the southwest and accidentally targeted a "hot zone" below that.
Since I wasn't prepared for hostile activity and was looking at my Pipboy functions, it didn't end well!
Therefore I am asking for a Map Zoom function to be added, so when there are a large number of waypoints grouped together, I can pick a specific one.
With iPads, you press two fingers on the screen and move them apart to zoom in.
To zoom out, you reverse the action.
This is what I would like to do with the PipBoy map.
