Close the Loop
Amp now offers a feedback widget that lets users send change requests directly from their website: enable it in project settings, add a script to the site's <head>, and allow the site's origin. Visiting the site with ?amp shows the annotation widget, where clicking page elements and writing instructions sends feedback that starts a new thread in the project, and the change is shipped from that thread like any other. After the first use, the widget appears on the site without ?amp until hidden.
