I submitted enhancement request FB24804559 for a system-wide scrolling screenshot feature in iOS. The idea is a “Capture More” option after taking a screenshot, similar to Android. iOS would continue capturing while scrolling, and the user could choose the exact endpoint. Ideally, this should work in any scrollable app where technically possible and save the result as one long image. This would be especially useful for Messages, Mail, Settings, social media, lists and other scrollable content.
