I always go straight for the item shop or health crystal(if the latter isn't close enough to the former) when porting to escape myself(Paranoia of a possible snipe still killing me after I port(however that works, anyway), I suppose.)
Alternatively another way is to quickly hold space, adjust the camera so you have horizontal sight on the target(ie. The Citadel, you know, big tower, can't miss it) and click quickly.
However, I certainly wouldn't mind adding some functionality to the minimap. Pinging locations, for example, is too helpful to have been left out in my opinion.
