Problem: There is no easy way to edit an entire page on the mobile site or mobile app. In order to make an edit involving multiple sections of a page, one has to either make those edits section by section or go to the desktop version of Wikipedia from the browser, both of which are inconvenient.
Proposed solution: Add a button to the top of the page that allows users to edit the whole page.
Who would benefit: People who want to edit Wikipedia pages on their mobile devices.
