Make groups more specific
I have over 5000 photos tagged #dog on my onedrive account. Understandable, but it would be wonderful if they were grouped into smaller subgroups. Like "German Shepherd" "Labradord Retriever" "Chihuahua" I raise service dogs and work at a doggie daycare. I have 4 dogs of my own and looking through 1000's of #dog photos for a white german shepherd i trained 2 years ago is next to impossible!
