If you’re a web developer and want to take a quick look under the hood in Safari, check out WebDevAdditions. This SIMBL plug-in adds a number of options to the View menu in Safari. You can toggle style sheets or view them in a separate window, disable parts of a page (images, links, tables, styles, objects, divs, or custom tags), outline parts of page (tables, block level elements, forms, links, or custom tags), or display image dimensions. Many options are invoked via shortcut keys. Want to quickly outline each element of a page and see its label and you hover the mouse around the page? Here’s how:

After installing WebDavAdditions, just press and hold the Shift and Control keys. As you move the mouse, each element is outlined in red and the tag is displayed.

You’ll need SIMBL, which is included in the download. And check out these other great SIMBL plug-ins:
