Tommy Feldt (ID: 000000a76c245072) Voted 5 ★ - Updated 03/19/2019 This is a brilliant extension! I use it daily in my work as an accessibility consultant. If I can wish for a new feature, I would like to have more information about each focused element in the log. For instance, you could present the accessible name of the focused element together with the CSS path. That would make it a little bit easier to distinguish exactly which element it is. You should also make it possible to right click the logged element to view it in the DOM inspector.
