Personally I find the App Library as useless as teats on a bore hog. To me it is like asking a total stranger to come in and rearrange all the items in your kitchen and pantry, or rearrange all the books in your vast library, or rearrange all the tools in your garage, etc. Why on earth would I ever do that? The answer is, of course, I wouldn't. I have enough brain power to organize things in a way that makes sense to me. I have no reason to allow Apple and its app developers to decide where apps get placed. If a person is so weak minded that they can’t organize a few dozen apps on their own, or they prefer to just follow whatever is forced upon them, then they have a lot of issues to tackle. But for me, I would never use the gawd awful App Library and I’m angered that I can’t hide that monstrosity.
