I've been gone for a while and I'm just getting back into it... does anyone still use QuestHelper?

I see Blizzard added their own version of it, and frankly I don't like it.

But when trying to use questhelper, it just seems to be all messed up now... Like it shows the blizzard "mob areas" for quests and stuff and I can't turn it off.

Does anyone still use it, if so, how do you go about using it?
