It has some neat features but in terms of customizability it fails completely.
The template system is ridiculous. Having to switch back and worth between pages to edit colors is retarded. I want one page or file that makes it clear and simple enough what you are editing. Why not let us edit a single CSS file?
If you have the patience to mess with it and learn the darn thing, good for you.
A warning to anyone thinking of buying this product: its great if you want a cookie cutter site but if you want to really customize the layout and design... good luck with all the hard coded template functionalities.
Maybe I'll come back to Xen in the future if the template system is simplified but until then, I'm going back to FREE alternatives.
So, how does one get a refund around here?
