The Photos Folder is not a useful tool if we are not able to decide what shows up there. I am using Dropbox to back up a Mac, so photos that are on my Mac are in those backups and also stored in other folders on Dropbox. Therefore, in the Photos Folder there are duplicate copies of each of those photos. I cannot delete either as they are on Dropbox for different purposes - one as a backup and one as part of my photo organization system in Dropbox. Without the ability to hide photos from my Photos Folder, I will need to find another way to organize my photos.
