A more visual way of showing recommendations
Top Shot is one of the most useful Google Photos features, as it allows you to choose a better photo from a selection of similar images you've taken. It's been around since the Pixel 3 launched, and there's also a little suggestion chip that pops up to remind you to use it. It looks like that chip could be replaced by a new row of image previews, or at least that's what Google is currently testing on some users.
