There are so many broken skillpoints, it is hard to remember which zones are 99% and which are already 100% without having to pay crazy stupid amounts of silver to waypoint in and out. to each one and write them all down in a notepad file.
Edit to clarify: The icon would go next to the zone name. For example, when you 100% Diessa Plateau, a little green check mark goes next to the zone name.
Cmon Arenanet. You had this feature in Guildwars 1 with Vanquish and Conquerer, etc, you cant add an icon when a zone is 100% complete?
