Adobe made some pretty serious changes in Photoshop CS4, especially in the workspace. And while some of them, like the new Application Frame, will take some getting used to (and are optional), they’re changes that are long overdue. Each new version has piled new tools on top of old, and important bits and pieces were getting lost in the shuffle. In fact, you’re liable to see several “new” tools in Photoshop CS4 that aren’t really new at all (like the Hand and Zoom tools); they’ve merely clawed their way back to the surface after being buried. As a result, a few tools have been cut (stay tuned to find out which ones).
