I'm looking at 3.0.4 for the first time and using the "Simple" theme.
With Firebug, I see that it calls a css file called "debug.css".
I can't find any info on this file, except that it's called from framework/dev/DebugView.php: and framework/templates/Controller.ss.
What does this file do and, if it's just used for debugging, why does it show up on Firebug when no errors or debugging are taking place?
It's overriding layout.css. Should it be doing that?
Do I need this file?
What is it for?
Can I get rid of it?
