Archive Chat History

I noticed that the longer I play the campaign, the longer it takes for Franz to respond to me. Even simple things like the results of my rolls. Perhaps it'd be a good idea that the chat history on screen only holds, say, 30 chat bubbles. Beyond that, you have a click a button that takes you to another screen like the character sheet where you can see the chat history further. This might help improve the speed of Franz as the campaign prolongs (I have 1gig broadband, playing on my PC. It isn't an internet issue).
