I always wondered about, if xara can handle all the e-commerce features on its own and the answer is simply NO
So now can Xara handle plugins or outside code and with all the posts that I see in this regards there are ton of problems with that too, specially in mobile setup.

I also know that there is Toms ecommerce feature but I think it is very limited to what can be done compared to other platforms.

So am I correct to say that Xara is not made for ecommerce website and that it is good just for informative sites?

I just told a friend to forget doing ecommerce with xara. I feel confident to have told him this, because I personally if serious about it, would not use Xara.
