It UI is used for menus, should they be marked Static? If so, would this include movable UI objects like sliders, scrollbars, etc?
The static keyword has nothing inherintly to do with the UI; it just means that you don’t need an instance for that specific member. I suggest doing some reading of the MSDN docs, and perhaps check out this quick code sample of mine here: Players number - Getting Started - Unity Discussions
Eh, I meant marking the objects as Static in the Inspector…
explanation of what that checkbox does… having said that, the new UI postdates that description, I’ve no idea if the new UI is even detected by those game engine systems 
Ha, ok, I am an idiot. Sorry about that!
