In-game Framework?

I’m looking at creating my own somewhat Framework for easy access to functions etc.
I want this for easier workflow and direct call of required functions without having to create paths within every script.
BEFORE anyone says about “It’s just a few words” this is personal preference that I want for my own work flow.

Does anyone have any suggestions?
Personally I’m looking at using _G or shared for global management. I.e. Transition management etc. Such as:
_G.Transition:new()

That way it can easily be called from anywhere throughout my game without having to create Paths back to it.
