In ages past on smaller screens I would code on the left, then have some supporting docs open on either a tab or a right-hand screen. But these days on my Dell 32" coding on the far left isn't that great, you actually have to turn your head. I now split off a little left handed tab which I use to edit headers in code, for example includes, constants, enums, structs, variables and so on. Then just left of my natural forward eye position I have another tab for the rest of the screen and the code.
