The new Archive feature recently spotted in Google Photos is now rolling out to all users, but it has an extra trick. While the Archive button lets you push more mundane photos (scans of receipts, screenshots of a random tweet, or maybe particularly personal photograph) out of the main Photos display without deleting it, there's also a new suggestion in the Assistant tab that will use its machine learning skills to find likely candidates for you. Of course, you can manually archive photos any time you like (they'll still show up in search or inside albums), but if you already have a significant Photos catalog this should make things easier. Whether you're using Android, iOS or the website, the new option should be there.
