It would be nice to have the chat log available inside the chat tab, instead of having an extra tab for it. The history could be loaded either: - "automagic": when the scrollbar hits the upper limiter (this how quassel does it) - or showing an inline button "show history" (or something like this), which loads then the previous 100 messages or previous session. Also it would be nice if the history would be colored then, see bug 328351.
