I appreciate your suggestion, Acorn.

I posted a pertinent question to Matt, Xara's CEO (as far as I know), but he doesn't reply. I expect Magix to duck any such question as well.

I had in my post a link to a joint/partnership page Magix/Xara: https://xara.kayako.com. It might be an older page and possibly the relationship between the two 'partners' has cooled over the years. However, you'd expect Matt to address the issue and shed some light on the whole collaboration and also reach out to Magix to prod them to do the same.
