- Allow to use a dark theme on all panels. I remember that for a short time, aurora had the dark themes on the html, css panels. It was great, but then it was reverted to the white background. It would be cool if there were a setting to choose the dark color theme. I loved it.
- Add something like firepath. A firebug extension, that adds a panel to test CSS/sizzle (jquery) selectors, and highlights the selected nodes. This is an extremely useful extension for me. If enough people agree, it would be good to have it integrated in the developer tools by default.
I'm working on that. Screenshot: https://bug836233.bugzilla.mozilla.org/attachment.cgi?id=719...
Keep it up, can't wait to ditch Firebug.
