That is a screenshot of my macOS desktop. It could be simpler, but as it is it does what I need, and want. When I need to use an app, I simply hit command (⌘) space and start typing the app name to launch it. That is, I use Spotlight.
Wouldn’t it be great that iOS could be customized like that too? Preferably it would be a setting, that would allow to turn off the visibility of all, or any app on the phone. Then, to open an app, one would use the Spotlight as well.
Maybe Apple will do something like that, one of these days.
