With the release of foo_uie_tabs for foobar2000 0.9, here's my latest setup:

Since foo_uie_tabs cannot put the tabs on the side, I give more vertical space to playlist view by moving the Volume & Seekbar sliders & the playing mode beside the menu, and put QuickSearch beside the buttons. I also remove all captions.
Here's the layout:


New features:
- Gapless indicator (using custom GAPLESS tag) beside T# and in trackinfo.
- Color-coded multi-CD's (each DISCNUMBER has its own color) shown in T# and Album.
- RG? column shows positive or negative RG adjustment.
Forgotten Credits:
- The buttons are HmmXP from
this posting. Hehe sorry...
Additional Plugins:
- foo_uie_tabs
PM me if you want the fcs, trackinfo script, or whatever.
