Early in 2017 I filed an issue against WAI-ARIA Authoring Practices (APG) requesting a change to the menu navigation pattern. Despite a great deal of feedback in agreement, it languished.
I’m looking forward to taking this pattern as well as the linked ones for a spin. I’m hoping for an opportunity to find at least one of these in use in the wild, preferably coupled with research with other people with disabilities. Barring that, it’ll be fascinating to find out which one I like better.
