For "Old Toad" Only: Photos vs iPhoto: Features and Capabilities
Hello Old Toad,
Superb job on your comparison of iPhoto / Photos. ( For some reason, I was unable to reply directly to your thread.)
Can you consider adding an additional element to your chart ? "Can display Keywords under Thumbnails".
As you know, for the first 10 years or so of iPhoto, it had the ability to display keywords under thumbnails. This feature was removed from iPhoto a couple of years ago. As a result, many users switched to Aperture, which still does have the ability to display keywords under thumbnails.
As a result of Aperture and iPhoto being discontinued, many are searching for this feature again. Your chart would quickly answer this question and may help this feature, (utilized by science and industry), get added to a future version of Photos.
Thanks for reading.
