I would love to have a way to only share select photos from a gallery. Use Case: After photographing an event, many people want their photos (From guests, vendors, etc), but don't need to sort through them all. I'd like to be able to share photos with multiple people without them seeing the whole gallery or making new galleries. Thanks, let me know if this was enough info.
