alt Hacker NewsI never have any window in the fullscreen/maximized mode. Some are pretty large, such as IDE, and they sometimes touch one or more edges of the screen/dock/panel, but never occupy the entire space. That was true even on my 14in MacBook with 125% DPI.
That said, I am a huge fan of manual window management.
I hever have any window in fullscreen, but I always have all windows maximized (obviously except the ones that can't be maximized, because of course settings couldn't possibly be made maximizable, what, that's crazy talk).
