I'm sure it won't dissapoint us! It must be so cool to do somehting like this on you free time (if you have any..) and see how people respond positively..
Well I found the hidden option, it took me a while to realize what you ment by OSM,(dah!) but i found it.. jajaja.. The only thing still to personlize is removing the info bar on the contact list window and the space left by the publicity in the convos, and adding the "always on top" button on both windows and the exit button in the contact list window, which i miss, but i'm asking for to much, ain't i? Those are minor datails anyway..
As i said before, great job. I'm doing the same carrer as you, and i know it can be very demanding, to the extend of not being able to do anything else. Good luck on that!
