There are a lot of features from Web Style that have been incorporated into Web Designer. Including those stretchy buttons that get wider if your button text is longer.

One of the things that Xara does well is to look at a feature that works in one program and figure out how to use that feature in one of the other applications. For example the Extrude Tool has some of the technology of Xara 3D. And some of the things they figured out how to do in Xtreme 4 have found their way into Web Designer.
