but the same principle applies
I completely disagree. Doubling the cached messages but only showing the last half by default is a very minor change in how quickly messages disappear and almost nothing like archiving the chatterbox for an extended period of time.
I like the idea. But I doubt it will make it to the top of the to-do list of anyone qualified to make changes to the chatterbox. ):- tye (but my friends call me "Tye")
