Just came across a post about this little gadget that should help out with any kind of web development, for example:
- Outline table cells without modifying your page source
- Manipulate IE browser settings for the current page only
- Resize the browser window to standard sizes
- Visual ruler to help with alignment
- Validate page links (including CSS links)
And a bunch of other toys I have yet to play with.
