and a global question - what was wrong about using Public variables from the App package comparing to forwarding the same values via arguments to functions/methods?

Global variables are appropriate when we use them as a singleton (IMHO any singleton is a design error, and we should strive to exclude it from the code base). In our case, global vars are used only to read flags. Due to the fact that we directly throw them inside our functions, we have high coupling.
To make the code more readable and easy to change, in this PR I partially isolated global variables from implementations.
