This is very useful in identifying why a certain rule is not being executed, for example due to a cascade of rules. The Layout tool is extremely useful in viewing any settings related to padding, margins, offset for any element. Thanks to this, there are no more border pixels set in debug mode to help me with borders and margins!

The JavaScript tab gives you access to all the scripts loaded by the current page. Tip : make minified script readable again by choosing Format JavaScript, a super helpful little tool.
