my only gripe with the msn integration via jabber, to add a buddys msn account to youur list - you have to add an account name thats like 100 characters long
example bob_smith%hotmail.com@msn.jabber.co.uk
that example has to be thier "jabber" account name, if you are adding from the address book. So they dont exactly allow you to add MSN accounts, but if you type the MSN account as shown in the jabber field of IM in address book, it can be done
edit - i faileed to mention that I would love to see a change in the way iChat handles contacts. If you are using your jabber account and AIM, 2 ichat windows show as if you are using iChat and enable rendezvous messaging. I would love to see all three windows be thrown into one - and support for meta data ala adium. This way if a buddy of mine is using his jabber account and AIM account, I will only see one NAME instead of 2 in 2 different windows
a little thing, but i think important enough to mention
other ichat interests
h264 isnt properly implemnted into ichat, and the current adc does not support multi audio/video conferencing. the video when you do conference is very pixelated - and im using an isight over a T1
video with AIM is implenented really well. Now i can start 1 way video and 1 way audio conferences with AIM users just like iChat users - and i notice that a lot more people now have the phone//video icon beside thier name - even if they dont have a web cam//mic - i guess it shows that you can start 1 way audio//video
iChat now supports profiles - which is something a lot of us wished we had for a long time
you can set your away message as the current track playing in iTunes which is nice
tabbed browsing does not exist in this build
the drawer effect is really nice for groups in ichat. instead of just opening, the groups now slide open - sort of like the drawer in panther's mail.
hmmm - cant think of anything else at the moment
will update if i do
