An update to Adafruit's Macropad Hotkey project with a few modifications:
- Rotary button no longer is an action, instead it turns on/off the displays
- Macros for Blender, Safari, a MIDI drum kit, generic number pad and Zoom
- Support for HID consumer control codes
- Support for mouse buttons
- Support for sending MIDI notes
- When no HID connection is present (power only), keep LEDs off and provide a message
- Mount filesystem as read-only unless the encoder button is pressed on boot
- Refactored the code to make it (maybe) easier to modify

These updates allow for you to use Hotkeys with GarageBand, play/pause music, send mouse clicks, or easily issue app shortcuts.
