Apologies if this is a very foolish question, but has this feature been integrated in 1.3.9? I've recently downloaded that version, but I haven't found any such function.

The previous poster more or less summed it all up. An autologging feature is an absolute must for a poorly organised chump like myself and lacking from just about every Mac MUCK client. I don't mind if it generates a new file for each session or appends each session to one super-log for that world. Many's the time I lost a good bit of fiction by closing the window and then, groaning, realizing I hadn't logged it.
A notificatin feature like Adium's dock icon, or even its use of Growl would be really handy and make this program much more useful as a window that can safely be left in the background,w ithout having to paranoidly check it every half a minute.

Other than that -- brilliant software!
