I find the current settings editor very weird because I can select "rows" within:

It is also an accessibility nightmare, because a blind user will lose time focusing that list and its elements when what he should be focusing are the actual controls, just like a form in a HTML page.

We're currently using the focus to "expand" the description. This adds to the confusion because by selecting a row, the list relays out and other items move down. What we should do instead is present a Read more link, which would do that expansion, for each element.
