I have been playing around with this feature for a few hours and have the following shortcuts set up so far.
1) Music controls for playing my music mixes (get-up, favourites, music, chill) and select playlists. It's weird that new music mix is an option, but not the rest.
2) Quickly texting my friend when it's time to leave for work (we carpool with another colleague).
3) Calling home (to check what to pick up for dinner)
Otherwise, can't really think what may be useful at the moment. I am using the Siri watch face and have the Siri app replaced with the shortcuts app.
What about you?
