This is an alpha version and I know of quite a few problems (no critical ones though).
The code is messy and some parts are not even used at all.
This is what it looks like:
compact mode:

extended mode:

extended mode with large albumart:

Download: navigator
I'll try to give a short description of some of the features.
(LMB and RMB refers to clicking the left or right mouse button)
The info about the current track will scroll if it doesn't fit.
Actions:
Resize: LMB and hold on time (upper right corner) then drag
Toggle mode: RMB on time (upper right corner)
Progress bar: LMB and hold 'skip' , RMB and hold 'scan'.
Albumart: LMB on it to toggle size
Codec/Replaygain info: RMB on it to toggle between the two.
Album-/Genre info: RMB on it to toggle between the two.
Trackrating: The five blue squares turns white according to rating (using the %trackrating% tag). LMB on one of the squares will find the next track in playlist with that specific rating, and show the result in the box to the right of the rating. Double click the result to play it, or press the - button to the right, to empty the box.
Buttons:
:B: show/hide foobar main window
Symbol to the left of :B : LMB 'play/pause', RMB 'stop'
<: LMB 'previous track', RMB 'Start this track over' (I think I will change this)
>: LMB 'next track', RMB 'random track'
s: LMB open 'Search'
g: LMB open 'Playlist generator'
x: LMB 'exit foobar2000'
n: LMB Show/hide a small "remote" used to skip to the next/previous artist/album with LMB (RMB to show the result in the box to the right og the trackrating).
/\ and \/: LMB 'scroll playlist (slow)', RMB 'scroll playlist (fast)'.
<(playlist): LMB 'scroll to current track'.
Try left and right clicking everything and you might find something I forgot to mention. If you look for a 'volume control', you won't find it, but maybe I'll add one later.
The progress bar is by tk32, but I have done some minor modifications.
Thanks to danZ, tk32 and other people who helped and inspired me.
Btw: I don't really need requests and bug reports at this point, as I've got more than enough to do already, and I haven't got alot of time at the moment. But, of course it doesn't hurt to mention the ones you come across, just don't expect me to fix them straight away.
Edit: For some strange reason foo_ui_columns seems to cause a problem, even if it's not being used. The playlist should scroll to show the playing track in the middle when you skip. If it doesn't, or other strange things happen, try removing foo_ui_columns.dll from the components directory.
