Is there a way to stop an app creating its own space at the back of the stack when you maximize it? Is there a way to stop an app creating its own space at the back of the stack when you maximize it? I like to have my apps in the same space always but they keep jumping around to the back of the spaces stack, any help appreciated! 

I'm using macOS Sierra.
Full-screen windows always appear in their own spaces. This has been the case for a while. There is no way to change it that I am aware of.

The settings that affect which space an app can be in only apply to non-full-screen windows.
