Ok, that kind of timestamp, native timestamp feature, is quite useful.
The theme I was using is http://adiumxtras.com/index.php?a=xtr...tra_id=4430 It put a timestamp for every message sent/received (haven't noticed how annoying is before ;-) )
If I think of it, what I picture is maybe less annoying than a timestamp for every message. A timestamp assosiated to status changes will be great, and "maybe" it can drive the iPhone behavior that you want :-)
Best regards!

Great Job! The only thing I miss is time stamps... I have read in limitations "Native timestamp feature is not possible with Adium (yet!?)." but the previous theme I was using (iPhone) have them... BTW it's awesome!
