RedQuits

Have you ever tried to close an application with its red button and wondered why it is still open? RedQuits changes this. All programs now quit and close all open windows if you click the red button.

In macOS if an app has a window open, you can click the red x on the top (or command-w) and close the window. But that doesn't always quit the application. Some do, others not. App's that have no windows open still take up some ram. If you want to exit the application entirely, then you need to go to the top bar by the apple, click the name of the app, and select “Quit [name of app]” or press command-Q.

RedQuits changes this. All programs now quit when there's only one window left for that program. If you want to quit and close all open windows of a program, just uncheck “Quit only when 1 window is left for that app.” in the preferences.
