It would be very useful if we had either a way to drag/move open channels around in the chat list, or at least set a sorting order. Right now, for instance, my butler's channel and the global chat are almost completely at opposite ends of the list (my butler is fourth from the top, global chat seventh from the bottom), making it impossible for me to see when there's new activity on both at once. The ordering of the list is also almost completely random.
What we need to do is either be able to set an order, or at least set a sorting order — and I suggest that probably the best default sorting order would be "most recently active". "All groups first" would also be a good option. At the very least, even if we can't change it ourselves during play, the default sorting order should push logged-out players to the bottom of the list to keep as many as possible of the active/available channels visible at once.
