At one point, a couple of days ago, I had a CSS reference panel on the right-hand side that told me which CSS properties are supported by which IE version. I've been searching high and low and pushing every button, including a reset to the full layout, but can't get that panel back. I'm not talking about the Inspector or the Help reference file. It really was a panel.
[Edit: I found it. It was the Inspector after all, I just have to put the caret inside the style block for the Inspector to switch to the CSS reference mode. Great feature, by the way!
