On git clone https://github.com/roots/sage.git no Controllers in the app folder. Is there a reason for that?
What you mean with Controllers? If you mean soberwp/controller, that package is not used anymore in Sage10. The master branch of the Sage repo is Sage10.
Sage10 works with View Composers: https://roots.io/working-with-composers-in-sage-10/
If you want to stick with Sage9 just clone the proper tag https://github.com/roots/sage/tree/9.0.10
Thank you, I was thinking that I am going mad.
I recommend you to check Sage10 though ;D
