I was trying to understand how Arkshine did it in the AdminFreeLook module (
https://github.com/Arkshine/AdminFre.../master/module ), but I don't understand shit. I think I have to wait until he explains something.
By the way, Orpheu is much more complicated, especially that it hooks functions registered in signatures and used in plugins. I just cant get to read that thing in the code and I dont know what is what in the Orpheu source.
