I sometimes use Cover flow in iTunes but other than that to me it is a waste, but I am convinced there are others who wouldn't want to be without it.
Wait! Cover Flow in iTunes 12.x with OS X 10.x?? How? Where?
And by Cover Flow I mean the carousel-style of album covers that could flow across the top third of the iTunes window. This could be another example of "correct OS X terminology", eh?
On a Mac since 1984.
Currently: 27" iMacs, Macbook Air, macOS 10.15.x,; iPhones, iPods and iPads galore!
