Growly Photo for Mac

Growly Photo does not import your photo files, it just remembers where they are. Within Photo you can create a structure of groups and folders as simple or complex as you like, to make finding and viewing your photos absolutely easy. At the top level are groups, for example you could organize your photos by year as in the screenshot above. You can also have groups for family, animals, collections, trips -- whatever you can think of. Each group contains folders, nested to any depth, and the folders contain references to your photo files.
