If you're already messing around in the area, I might also toss out the idea of a "Quit" action. (We don't have an issue tracking this, but we've mentioned it a pile of times as a team). This is like the "Close Microsoft Edge" button:

Or "Exit" in sublime:

It's just a simple action to close all the windows, which also then triggers the "save all windows" behavior. A little more straightforward than "killing it in task manager" 😛
