Aptana: Apt for Success?
The line-up of cross-platform open source apps is pretty impressive, except in one area: Web design. Until now, all we've really had is Nvu, which is certainly very easy to use, but rather limited in terms of more advanced features.
But now here's Aptana, a "robust, JavaScript-focused IDE for building dynamic web applications". It's still early days yet, but judging by the screenshots, it looks promising. (Via Digg).
