"Hold Option while double-clicking a window's corner to expand the window to fill the screen." - this is the most important tip for macOS, IMO. I still don't understand what's in their heads that they don't maximise Safari/Preview to the full width by default.
I have 32" display and I'm using all my windows maximized, I just don't ever want them side by side or something like that.
That’s how you work, though. Having Safari fullscreen is really not great for me. Nor Preview. Actually the only thing I have fullscreen (not in its Space) is Xcode.
EDIT: I meant window maximized to fill the screen, not fullscreen, which is what option-double-clicking a window corner does.
