Website themes and elements (v11)

[yjs]

In the design gallery there are now different types of website themes:
General - Mobile ready
General (with subcategory 'legacy') and
Business specific

a) Is there any structural differences between the legacy category and the other general themes or is it just that there are no plans to develop the legacy themes further?

b) What's the situation re mobile variants for the business-specific templates?

c) I have a couple of codes for free business templates from an earlier version of the software. I assume these are still valid to purchase business templates?

I've never used a theme 'as is' but frequently take elements (colour schemes nav bars, buttons etc.) from different themes and would love to organise these elements with my own naming for easy retrieval, in a way which can easily be moved between Xara versions. Is there an easy way to do this? Angelize already wrote a nice tutorial on how to do this for colour schemes.)
