limit number of messages in a muc window
(first off; I don't know if this is already a ticket or a feature.. I searched for some keywords but found nothing)
In some groupchats the number of messages accumulates very quickly. so quickly even that after a while gajim seems to have difficutlies coping with the large amount of messages causing the window to flicker every time a new message arrives. (commonly seen in irc chats ;) ). pressing "clear" solves this, but it has one annoying side-effect; you also lose the last few messages. usually, you don't really want that (you just have no choice). I though it could be handy to have an option somewhere that says "maximum number of messages in a groupchat", which I could then, for example, set to 1000, to prevent a memory-overload. I wouldn't have to press clear every now and then meaning I could always keep the latest messages.
also note that it might not be very obvious to a newbie that you have to press clear if the message window flickers... this would prevent unnecessary dramas ^^
