I've just tried to access the chat room logs on my website via the control panel and it took an absolute age to load because it loaded everything from when the chat room first started (back at the end of June this year). Once it did load, scrolling through the logs was slow.
I'd therefore like to suggest that chat room logs could be made to open or download as text files, which would be a lot quicker to access and read than on the admin web page.
A second suggestion is to add a way to clear the logs via the admin control panel, either completely or for a specified period of time (e.g. all logs before a certain date or more than say a month or 3 months old).
Finally, I notice that in the logs special characters such as apostrophes are preceded by a \ (backslash). I know this is an escape character and this issue was resolved a while back for chat rooms themselves but it would be nice to see it sorted in the logs as well.
