This is a feature in Ruthless Launcher where to show all of your hidden apps in one place, all you have to do is go to the bottom of the app drawer, then scroll down a little more and hold it. This would then show all of the hidden apps in their own category and it is much easier than going into the settings and then toggling to show them in with the rest of your apps.
Most likely, if someone is hiding an app there is a reason. For example, I have my dating apps hidden, but I want to be able to access them fairly easily.
