One of my absolute musts in a text editor is a feature that prompts for a command, pipes the selected text into it and replaces it with the command's output (for Visual Studio Code it comes as a plugin). So "Ctrl+A, Ctrl+\, 'json_pp', Enter" and voila, formatted JSON in my editor (Ctrl+\ is what the command is bound to). Also works great with grep, sort, awk...
