This right here tells us how much time you (haven't) spent with the stock moto ui. You can indeed hide apps in the app drawer.
Reading comprehension. Try using some of it.
What is there to comprehend? I really don't see any other way to read that. Either you said it would be an improvement to be able to hide apps or you didn't, but it looks like you did. Please explain to me how I can read this in the way you apparently meant to write it. Because it looks like there is a disconnect between your brain and your fingers...
*edit
Unless you meant delete instead of hide. But you wrote hide, so I'm sure you can excuse my confusion.
When read together with the rest I indicate the the only improvement to the app drawer via Blur is the ability to hide apps you don't use. That indeed is an improvement over the stock app drawer.
