More variable types

I have noticed that when creating variables in the new procedure system (which is great) there are only logic, integer and text variables at the moment. What could be great in future versions would be the ability to create variables to store items, entities and players in for easy reference. some examples of what you could do with this include transferring inventory data to multiple locations, storing the inputted item in a GUI so you don't have to reference the slot 10 times, specifying players that have triggered events in the past and referencing entity data efficiently. I hope you consider these ideas, and keep up the good work!
