Section editing is important, we all need it, and it isn't available on VE on mobile. That's a problem, focus is important. That's why we're working on this.

Was it easier for you to stay focused on where you were within your edit? Was this expected behavior? Any and all comments are appreciated! Feedback will be summarized on the main project page.
