IntelliJ is indeed java-centric (and not light-weight), but the front-end coding environment is top-notch. I've tried going back to a light-weight text editor (I'm still a sucker for TextMate) but I always come back to IntelliJ. The code completion for HTML/JS/CSS is phenomenal, and the way it intelligently switches syntax highlighting schemes regardless of filetype cuts down on my numerous, numerous typos (for example, if in app.html you write <div style="foo:bar" onclick="foo('bar')"></div>, the HTML, CSS, and JS components will all be syntax-highlighted appropriately). It's also great for XML.

(I also happen to work on an app with a Java backend so it's a no-brainer, and the company's paying for the software...)

EDIT: Just realized you were referring only to the CE, which I've not used. I'll leave this here as a _non-sequiter_ opinion on the paid version nonetheless.

Perhaps it's worth paying for it for you? Calculate how much your time is worth, and compare to how much more productive you would be.

I'm using the free version, since I'm only doing Java, but I truly think IntelliJ IDEA is great[1], so I would pay if there was no free version.
