I'd just like a keyboard shortcut to be able to tab between open conversations. This could be similar to how both Ctrl+Enter & Tab currently go between game world, local chat and one group/IM chat, but would let me tab through each of the open chat windows I have (ie with different groups/individuals). It's a big need for people who love those keyboard shortcuts! Perhaps add in the Shift key for this feature?!
Also, I find myself not noticing updates for groups/individuals I have opened up in the top area as my eyes aren't drawn up there throughout normal game play. My thought was that it would be nice to have the ability to slide their positions around, say below Local Chat, where my eyes are drawn to more often. Then I'd notice chat that's happening that I'd otherwise not see so often. Even the ability to change the order in the top area would be sweet!
