chat rooms (conference) history should be grayed out
Currently, in peer-to-peer conversations, gajim displays a brief history of the last conversation, in gray. This is an awesome feature, because it provides information without being intrusive.
However, in chat rooms, every time you join in, you receive a HUGE log of what happened recently in the room, even if you were not there. Now, this is okay, but it would make a lot more sense if there were no colors - only gray, just like the "peer to peer" conversation quick history - and/or provide me with an option to disable that feature for chat rooms.
Because otherwise, there is no easy and efficient way to visually make the difference between messages you may not care about (the same logs repeating for the 5th time today) or messages that need your attention (real people talking in real time in the chat room).
