Don't forget you can go to your Home/<user name>/.yahoorc folder (have to click View and choose to be able to see Hidden Files), and once there, continue to the gyach/logs directory under .yahoorc, and it will show logs of all your chats. I found this out by simply looking at the little blurb it says at the beginning of a PM window "logging to file Home/<user name>/.yahoorc/gyach/logs/<yahoo friend name>/<yahoo friend name followed by date and a bunch of numbers>.txt, and tracking down that directory as above.

But yes, a more automatic way of looking at logs & history would be nice! :)
