In the past few versions of winamp (free), I have not seen the minibrowser function. Is it available only in the Pro version now?
The minibrowser was renamed ("Now playing") and moved to the Winamp library. This change was made in Winamp 5.0.
If you haven't installed the library, then you have no minibrowser.
Station info shows infos about the current playing station. I don't like it, and think it blows up Winamp, so I'm using Dro's Die Browser Die plugin
