Few things I would like to recommend for the plug in if you have used windows media player there's an option which a menu hide bar when you scroll your mouse in that position the menu bar shows up so I was wondering if you can create something like that for the messenger and one more thing in the previous version of MSN Messenger when you take your cursor next to a contact a little messenger plus butterfly icon come up next to it and that's not happening any more with the newer version of MSN Messenger if you can fix that please so we won't have to right click on a contact to get extra features.

The Plus icon has been moved to the top of the main window, next to 'MSN Today'.
As for the menu bar thing, I think that'd have to be part of Messenger itself.

Yeah that probably would have to be a feature of MSN Messenger, rather than a plug in.. although someone may be able to create one.
