It occured to me today it would be cool to mark waypoints on Live Map so when you look at it later you still know where you were headed. Or where your secret base is. Give me feedback on ideas guys!
This is an awesome idea but would be very difficult. The reason is that the live maps are separate from the site and game and they have no idea who you are. You can set waypoint's in-game using REI's mini-map mod. And this mod is ok to use in EMC http://www.minecraftforum.net/topic/482147-11100-jan14-reis-minimap-v30-01/
