Allow people to unchoose a quest immediately after choosing it
Sometimes I've chosen a quest, then immediately realized that others were suggesting a different one in the chat box. And there's no way to go back! Seems like an easy enough fix.
For this and a couple of other reasons, we plan to make quest selection something that party members must confirm before it’s locked in. In the meantime, there’s no penalty to abandoning your quest and picking a different one aside from the extra clicking.
