To thin out the classic "central hub" that we see in pretty much every MMO, I think it would be a nice small feature to implement a toggle that displayed /shout messages in all cities or field zones in your chat log.

Could toggle it on/off, so if you were hunting for city specific quests you could simply view the shouts in your city or immediate area only. This would hopefully reduce the "central hub huddle" that we see in pretty much all MMO's.

I also feel that it is sometimes a trade off between doing solo content (such as gathering or farming) or watching for shouts during a quiet time on the server in a specific zone where I can't do anything.
