### And everything macOS keeps buried.

The readings, the switches and the shortcuts it never puts in front of you.

#### Stop at 80%, or charge to full.

A limit for every day, and a full charge before a flight.

#### What is drawing your power.

Watts in, watts out, and the apps burning it right now.

The readings macOS buries, put in your menu bar.

Percentage, time left, monochrome or not.

Charging state, calibration, and the rule that took over.
