Cinnamenu@json: Make "All Applications" optional

What would you like to see?

Here's how my cinnamenu setup looks like, very minimalistic, only what's really needed as an app launcher is there. I have enough apps though installed that using the "all applications" menu makes it impractical, so I never use it. That's why I'd like to also be an option to not show it, as there is for other options that I have already disabled. Thx.
