Hi. Thanks for submitting this PR but unfortunately I'm going to have to reject it. You can't extend App\Http\Controllers\Controller because that class isn't guaranteed to exist - e.g. the consuming application might be using a different namespace. In addition, as this is a package it should only use classes that it can install via Composer dependencies, so it will have to extend the Illuminate\Routing\Controller and retain the traits that I've already put on the class.

I think it'll be easier if I make these changes, so I'll close this PR.
