Holy crap — how did I never know about the nightly WebKit builds? (For those of you whose inner geek isn’t as sadly web-centric as mine, WebKit is the framework on which Apple’s Safari web browser is built, and the nightly builds are the versions of the application built every night from the current development codebase.) I stumbled upon them tonight, and immediately fell in love with the Web Inspector, a much nicer implementation of Mozilla’s DOM Inspector. Parts of it haven’t been implemented yet (hence its presence in only the nightly builds!), but it looks to be a great new tool, and a great way to debug my web apps in another browser.
