Over the years I have gone on about accessibility and how Xara's approach is lacking.

Here is a comprehensive rundown of what would be perfect in an accessible Rich Internet Application (ARIA): https://www.w3.org/TR/wai-aria-practices/.

To show how complicated it can get, read https://www.htmhell.dev/20-close-buttons/, which is just for a Close button.

I use PortableApps, which has free accessibility products: DSpeech & Virtual Magnifying Glass.
These could be used to check how poorly assistive technoligies fare with a Xara design.
