Don't hold back.

I agree. And I have made the same mistake too many times myself. What you have to do is just not link to the pages in the Mobile variant but do not delete them.

And to be on the safe side, delete the content on the pages on the mobile variant you don't want anybody to see. I discovered that when I rotated my iPhone, it showed a page I had not linked to.

I am going to move this to the Dear Xara forum which is where bugs and feature requests should be posted.
