I’ve been deep in the thick of web development on a few projects I have going in my research lab, and tonight I stumbled across a tool that I’m not sure how I lived without, the Mouseover DOM Inspector (or MODI). It’s a bookmarklet that creates a detailed inspector window for the currently-open web page, showing pretty much everything you could need to know if you’re the one programming that web page. Seriously, it’s the lightweight tool I need for the times when the Mozilla DOM Inspector is overkill; the only negative is that it doesn’t work in Safari. (Although that may change soon, since it appears that the latest version of Safari fixes the problem that prevents it from working.) This is definitely on my list of necessary tools in the toolbox of any web developer.
