My editor of choice is Emacs. I admit I've been impressed with VSCode, and currently use it for editing .vue files. I'll also use it for breakpoint enabled debugging when working with some languages. However, I don't foresee a sharp decline in my Emacs usage anytime soon, and therefore I'll sporadically step back and see if there are things to make my use even better.
Tonight, I was working on my elixir-mode and alchemist usage and config, and was restarting Emacs frequently. At some point I became frustrated by having to maximize the window (frame, technically) each time. Stack Exchange to the rescue! I learned two things from that page. First, on my machine at least (Ubuntu 16.04) ctrl++ will make any window full screen.
Second, for Emacs, I added (add-to-list 'default-frame-alist '(fullscreen . maximized)) to my Emacs config.
