Mojave: Disable Screenshot Thumbnail

I am really liking the new Mojave macOS. It seems to be very stable and of course, there are some nice new features. One of those features is screenshots creating a thumbnail which can be clicked on for editing. That is cool, but if you edit most of your screenshots in other Apps like I do, then it just gets in the way. This article describes how to turn off that feature if that works best for you.
