+1 for me too. This is one of the weakest areas in XDP that Xara really needs to improve. It´s probably the one that's keeping me from using Xara to it's full extend on a daily basis. A good text composition engine is fundamental to support all areas where Xara can be used as @angelize already pointed out. Adobe still does a much better job here - not talking about inDesign -, just Illustrator. As do Pageplus.
I agree it should be at the top of the list too, especially now that Xara is moving to desktop publishing with a dedicated application.
