Don't hassle with configs like that if you don't understand what to do. Use the default UI only from foobar 9.5.3.
It won't look that fancy, but if you try your default configs can look nice too.
I tried to create the image you shown with default ui only. I don't understand code to make text in other colors, but there should be a way to make columns have their own color if i see the titleformatting helppage ( $rgb(255,0,0)asdf$rgb() ⇒ “asdf” for example. ).
Can someone make up code for showing tracknumbers only when they are 1, 5, 10, 15 and so on? I could only come up with showing track 1...
Here what you can make with default UI in a few minutes. (don't look at my windows theme, it's default windows xp silver, when you use another windowstheme, a black one for example, all the grey parts will be black too).
