First Look: Dreamweaver CS4 beta

The public beta of Dreamweaver released by Adobe Tuesday delivers significant changes to the 10-year old Web design and development tool. Not only does Dreamweaver CS4 offer a complete overhaul of the user interface, it adds many new features aimed at the "professional" Web developer. In addition, the beta expands on the powerful (and easy-to-use) Spry toolset introduced in last year's Dreamweaver CS3 release.

Integration with the Creative Suite

The most obvious change to the program is Dreamweaver CS4's new user interface. The old Macromedia look-and-feel has finally been replaced with an interface that matches the other applications in Adobe's Creative Suite. (Dreamweaver was among the Macromedia products absorbed by Adobe when it bought its one-time rival three years ago.)

While this change will take a while for long-time Dreamweaver users to get used to, the new interface significantly improves the usability of the program. Panels and windows mesh together well, are easier to organize, move and hide, and the new interface provides the flexibility to create a working environment that's comfortable whether you're working on a 17-inch monitor or a 30-inch Cinema Display.

In addition, the program has taken its first step toward supporting a feature that's been in the other Creative Suite programs for years--SmartObjects. Dreamweaver CS4 now offers support for PhotoShop SmartObjects--you can drag a PSD file into a Web page within Dreamweaver, optimize the image for the Web, and even resize it. If you later update the original PSD file, a red arrow will appear on the image inside Dreamweaver indicating that the source file has changed. You can then click an "update from original" button in the Property inspector, and a new version of the image is created.

A professional Web developer tool

Dreamweaver has always been a powerful tool that has attracted both Web novices and Web veterans. This latest version offers a slew of new features aimed directly at those that feel at home working in raw HTML, CSS and JavaScript as much as they do working with Dreamweaver's visual, dialog-driven tools. In fact, many of the new features promote a workflow that involves working in code view alongside the visual design view.

The new related files bar, which appears between the document toolbar and the document itself, lists all CSS and JavaScript files linked to the page. (If you're using a server-side programming language like PHP, you'll see included server-side files listed as well.) By clicking one of the related files in this bar, you immediately jump to the code in that file. In this way, you can open a single Web page and immediately have access to other files the page references: quickly jump to the page's CSS file, make some changes and jump back to the Web page file to see the changes.

The related files bar really shines when combined with another new addition: vertical split view. Now you can see side-by-side, a page's raw HTML code and its visual design. Make a change in the visual view and see the code immediately updated or vice-versa. When viewing a page that has related files (for example, an attached external style sheet), you can see the visual design of the page on one side, and a related file in the other. This lets you edit the CSS code and see the changes take place visually on the Web page.
