In addition to being able to add Labels to Photos for the purpose of sharing/organising them (a separate feature request already here), we have to have the ability to apply a Label to a Folder/Album and not just individual photos.
I would like to be able to create an album, say “Good Pictures of My Daughter” than I can add pictures to regularly that I can share with family/friends. I want to be able to add photos to that album without constantly having to go, manually determine which are labelled and which are not, and then label them.
