When the final version is released, I hope there will be "something" inside the configuration of the plugin in Messenger Plus!'s settings. Now it's just the About-box there. I want WinAmp to be default, not WMP. And some others probably want iTunes to be default. Besides that, I have no negative comments, a great plugin!
Uh.... one more thing, the WinAmp controller buttons inside the conversation wasn't the nicest looking buttons I've seen... It isn't possible to see any difference between STOP and PAUSE!
What about using the buttons from WinAmps own "Windowshade mode" (the button between Minimize and Close in the upper right of WinAmp's main window) instead of something that looks like redused sized normal buttons...?
