Feature request: Activate When Plugged into External Display

[caseyWebb]

Hi, this is absolutely a "nice to have but not necessary" thing. It would be nice if there was an option to enable automatically when an external display is plugged in and disabled when it's unplugged.

I like this idea. As an alternative option, you could also enable when plugged in, disable when on battery power.

This would actually save me from quite a lot of reboots -- my Mac regularly crashes when connected to an external display and going to sleep -- disabling sleep only when connected to the display would resolve this perfectly.

Created an MR for this.
