This should be as easy as scrathing your ass..
... hehe...
No, seriously, this is very easy if you just got the hang of Msgplus API, and the Messenger API.... If I wasn't busy doing my other programming projects, I would be willing to do this, since this idea have been said several times I think, It was talked about just before Patchou made the "Contacts on Desktop" feature... I haven't been following the latest update in the MsgPlus and Messeng API's so I would have to do some research to get up 2 date, but I can't do that ATM..... But anybody else willing to do this?.. It shouldn't be very difficult if your up 2 date with the API's...
