I'm liking the "go to" option. That's a great idea! But for the other option, there's always the "find" button. If you wanna find a certain friend, you zoom out on the map that they're in and click find, their dot blinks red. If their dot is with a cluster of dots, what I do is go to the cluster of dots, then zoom in to see which is the exact dot I should be looking for. It's pretty easy, I mean I've never had any trouble with this and I find it to be quite useful enough.
