4k 39" 16:9 here, but it's a TV not a monitor. I'd also love more height, but I think we're stuck with 16:9's past 35" since monitors past this size aren't popular. While we're wishing, I'd also like curved please :)

I'm use Windows so AutoHotKey is my window manager: https://autohotkey.com/board/topic/79338-simple-window-posit...

Usually my main window is an IDE and it takes 50% of the center, and I'll have miscellaneous windows off to the left and right peeking out from behind it. Creating shortcuts to specific programs (also to minimize/maximize/close them) is also helpful as mousing to the taskbar is just not efficient.
