Use Adobe CC 2017.07 ... kick out every add-on software component using CleanMyMac X until you see this:
My concept works (tested on OS X Mojave) if you want a trouble free software workbench ... of course "they" want to trash the working software workflow ... as always since decades to bother creatives around the world and keep them as busy as much as ever possible with lots of software troubles every day ... and the next day ... and the day after ... till the next OS version.
The reason why Apple "Leadership" + Adobe "Leadership" software politics makes no sense. That's my experience after a very precise analysis of both companies over 20 years.
For Launchpad itself, you can just stuff them all into a folder. Just like iOS, you copy one app over another and it creates a folder, which you can name, and to which you can add all the apps you want. I use several folders in Launchpad, one of which is for all of my Dock apps. If they're on the Dock, I don't need to see them in Launchpad as well. This doesn't hide them, as such, but it keeps them more out of sight.
