Favorite Places

It would be great to have a way to tag your favorite places in a world in game. And then when you wanted to go there you could go into your list of tagged areas, click on the one you want to go to,  and it would give you an directional icon on the screen you could follow to get there. Right now I have been taking a picture of the coordinates and using the coordinates to get there but this takes a lot of reviewing the photo to make adjustments. Also, it would be great if you could tag it for others playing so that they could go in to their list of tags, click on it, and they could meet you there.
