Why Is No One Talking About Photoshop Libraries?

Since the 2020 update of Photoshop, I’ve noticed a considerable speed increase in sync speed and library items are almost shared live without delay. I’ve been playing around with the Adobe Capture App, and it’s been  fun and helpful. 
It’s been easy to take a photo of something and have it convert to a vector based file I could use in Photoshop. I then also discovered I could do it inside Photoshop directly without the Capture app. I could do this by opening up the file, clicking the little ‘+’ sign below in the Libraries Panel, and choosing whether I wanted a pattern, shape, colour range or gradient.
