[Feature Request] Option to enable Amethyst only when computer is plugged into external monitor

[malob]

System

• Amethyst version: 0.14.2 (76)
• macOS version: 10.15 (19A602)

What's the problem?

I have a 13-inch MacBook Pro. Most of the time I use it at a desk plugged into an external monitor. However, I occasionally use it on its own without and external display.

I find Amethyst super helpful when using an external display, but of little to no use when I'm not using one. I'd love there to be a setting that automatically disabled Amethyst when the computer isn't plugged into any external monitors, and automatically enabled Amethyst whenever and external display is connected.

I'd really love this feature. I disable Amethyst when I'm not docked, and in practice the menubar icon is often hidden behind the MacBook Pro notch.

I'd also settle for a shortcut key to enable/disable Amethyst.
