I've never used Chromium, but you don't get the browser's vertical scrollbar on the right side of the screen? I have it in Chrome on Windows. Moving it shows various categories right beside it and lining it up with them changes the content in the middle.

Yeah this is no good for Lion users (assuming that Lion hides ALL scrollbars automatically, right?)

I have one in Chrome 13 on Lion. What happens if you scroll?

Awh, I guess it's not a good hack then ',>/

If you have Chrome it should open in that.
