I had an idea that might have been brought up before. I was thinking when you go to a different area of a world, for example Kishibe Village in Mooshoo. How about some kind of stat that will let us know how many quests we have left before we finish the area. For example have one for Main story line and side quests. Something like this
Main 9/16 Side 3/4
So that would mean you have completed 9 out of 16 main quests and 3 out of 4 side quests. Just an idea, I love the game no matter what.
