WD wasn't combined into Xtreme 5, WD was extracted from Xtreme 5 and released earlier when the relevant work was completed. This is clear from the fact that WD/V5 web features are a substantial update to what was already in V4. V5 is a serious upgrade from WD/V4 html features because unlike WD, you can use all of Xara's drawing features. I gave my site a visual revamp to illustrate this.
Content aware scaling has been the source of a lot of talk since Adobe bought out the inventors of the original technology and stuffed it into Photoshop. Xara's implementation is the world's fastest and very slick. Xara's version does lack the ability to force areas to be removed before others however.
Spell checking and multi-stage transparency have been two long asked for features on TG. HTML was given priority because producing websites is more important for most than producing web graphics alone nowadays apparently. So what was done does seem to make sense, even though at first glance it appears somewhat disappointing.
