When you pick up lots of quests, your quest log gets full, and you have trouble finding ones you are going to complete right then. Nobody wants to spend 5-10 minutes sorting through quests . There should be a storing quests feature where you can drop quests into a quest storage. At the bottom of the quest book there could be a jar that says "Quest Storage" which is where you can pick up your stored quests and put them back into your main quest log.
This could really help! Somewhere on the boards I saw an idea for removing quests, but I think just storing them would be better. Think about it KI. Wizards, tell me suggestions and your likes! Thanks!
