hey Matonga~ not to distract you from your cool projects, especially Focusin, but have you ever considered writing a plug-in for Songbird using your coverflow or front row stylization skills? I know there is already a coverflow like plug-in for Songbird, but it's not really up to snuff the last time I tried it out (a few months back.) But the idea would be to not just make a functionally smooth and fluid animated browser of music and video files of sorts, but rather, make it useful for library management and compatibility of formats as a priority! for instance:
~ Right Click files to: "Locate on Hard drive"
~ Selectable default programs to launch different filetypes.
~ Assignable graphics for: No Album Art, No Video Cover, etc.
~ Allow user to select a frame (within the video file) to use as the static cover image of said video file(s.)
~ Right Click to access meta-data editing, etc. (or a flip animation to edit on the back of the cover image, maybe?)
Anyways, you'd probably make a huge splash in the firefox/songbird community if you created something like this, and you seem to have much of the concepts implemented in some degree of completion
