I have a bunch.
Launch Waze and turn off WiFi when I connect to Bluetooth in my car
Turn down the volume on one of my headsets when I connect, since otherwise it blasts my ear drums
I use Federico Vittici’s multi button for my action button: one press turns on the flashlight, press again within five seconds does something else.
Pull my next appointment and give me directions to it
Check a price on KEEPA or camelcamelcamel without using an extension, just share from that URL and run the shortcut
Delete all my disabled alarms, leaving those that are still active.
Play a random music album
Find the album of the currently playing song and play the whole album.
Backup all my tabs in safari to a file
Send the newest photo to a contact of my choice (works great voice-only)
