Pretty sweet plugin. Being able to limit the area of focus is massive for presetting and allowing someone else to get a focused view of issues with their content. It doesn't end there as there is a massive array of configuration options one can setup to help narrow the focus of less technical users (or declutter their own experience).I also really like how it checks custom post types as well as regular. The UI is pretty sweet and easy on the eyes. The links to documentation in the descriptions is welcomed. One might say it should link to the official docs, but that can be a lot to take in regardless of ones technical expertise. So the fact it links to a11y-101 instead is nice to see.
