Just a couple of nice ideas I would like to see in the future:
* Ability to see the quests (and maybe missions) I have completed in the Quest Log (L) Window, because when I want to help other people with quests, I would like to recap what the quest was all about which that other person needs to complete.
* Ability to close the Party window (P) in towns, which would disable the ability to be invited to a party (or maybe a button feature on the window which does this instead). Nothing is more annoying then doing a bit of business (with post ascended char) in, say Ascalon only for some level three player to have the cheek of inviting you to a party without even asking you and even when you do not even want do go questing.

That would also make it less frustrating for groups trying to find a monk, for instance. Many will click every available "Mo/?" in the area. Disabling the party screen would make it easier for them to know who was or wasn't available for the mission.
