I'm multiboxing with 2 chars - I'm leveling in Pandaria - and everything goes pretty well, apart from one thing: From time to time I forget to check the Jamba Questlog and then it happens very often to me that I suddenly realize that my toon did not accept a quest or did not finish a quest, and then I have to do the same quest again and this is really annoying.

Is there a better way (addon) to keep the quest log in synch, like something to have a better overview, or a warning tool which warns me when e.g. my master finished a quest and the slave didn't?
