[C++][Blueprint] Main menu and in game menu with basic game, graphics, controls and audio settings

So is this stable and acceptable for 4.13?
Im looking for something that will work with what i have. The Cardinal system broke my entire widget system and i ended up having to remove the Cardinal menu out of the project entirely. I was certainly not happy about it, but, any other system (advanced social and inventory system) would lose functionality (entirely) when adding in the menu. Removal and it would magically start working …

but, back to the topic at hand … does this setup work with 4.13 and is it able to be implemented into current projects? Can i use the same cast to system that i am using for my social system?
