Just imagine looking on someones profile page with all the clickable villages displaying and what oasis they have. Would be grand to be able to click those oasis on that screen and let it take you to it on the map or something.
So 1 click instead of 2 clicks and 2 seconds of looking at the map, what a bargain!
But in all seriousness, it seems practical, but not something that would really be used a whole lot by a vast majority.
It seems very useful, sounds easy to program, and wouldn't change actual game play except to save some time and inconvenience. Why aren't these the kind of updates we get?
