Create photo books automatically based on "favorited" photos.
Allow users to select an option when creating photo books that includes year (which you already offer) and "favorites." The favorites option would automatically create a photo album with all the photos that have been "favorited" by you or family/friends who have joined the album. Since I have uploaded so many photos and spent time favoriting certain photos, it only makes sense to offer this convenient customization feature as an option.

or hashtag the photo to create album by thematics or for people only with the pictures where people are (with my parents for them, with the cousins for my sister in law, etc) . Creating albums is not perfect, it s hard to find the pictures, to personnalise, etc... With some new tools it will incitate to create lot of albums !!! Im really interested in !
