Bookmarks in Reve let you save and quickly access your favorite images. When you bookmark an image, it gets added to a special collection you can easily filter to later — useful for marking your best generations, images you want to revisit, or work-in-progress pieces you're not done with yet.
To bookmark an image, just click the bookmark icon in the top right when viewing your image.
To find all your bookmarked images within an album, click the menu in the top right and select Bookmarked from the drop down.
