Same here. I'm usually a "single task" person (I like to focus. I know well that I don't function well when trying to do many things at once), so a single maximised window is always the optimal approach for me. This is also why I've never bothered with multiple displays, which most of my workmates love.

On the rare occasion when I need to use data from a window to write something on other (like something that can't be copied and pasted, or cases where I need to extract information but not literally copying, such as using some data points from a reference file in code I'm writing) I just use win+left and win+right to spliut the screen between the two windows (I assume that OSes other than Windows have similar hotkeys).
