The Photoshop 2020 Preset Manager only shows contours and tools. Where are the others?

I just spent wasted time doing the same thing,  I'm watching a training video on Gradients & he ' of course ' is using an older version of PS & what he was telling us to do, we couldn't because I could not find the gradients in the preset manager,  I know they have their own panel , but I thought they should have been also where he was telling us to go,  NOW I know & I just wish Adobe would have put out a message about this first. I hate wasted time.    And of course I just found your message dtd 11/22/2019 & several others that were looking ' like me '  .  Just thought I'd share 🙂 

An old Preset Manager panel was way more convenient. I could access all my swatches, patterns, brushes, and custom shapes presets from a single menu. Now in Photoshop 2020, this functionality is gone. It's a pity!
