Should be able to distinguish scrollback messages that current messages
Submitted by Guillaume Desmottes
As said in bug #602288, the chat UI should make possible to distinguish scrollback messages that current "new" messages.
We could do that by displaying the scrollback messages and then a "you joined the room" message but I'm not sure if TP says us when we received all the scrollback messages.
Another option could be to display differently scrollback messages. We should check if Adium themes have that feature.
