A good pocket knife or multi-tool like a Letherman or Gerber. I always have a pocket knife on me and a multi-tool in my car. Either one gets used pretty much daily.

Night mode is great but if you can set your camera on something perfectly still or use some type of tripod, night mode will change to astrophotography mode after a couple of seconds. Then you can take a 5 minute exposure that saves both a nice looking image full of stars as well as a time laps video. Do this someplace really dark and point it in the direction of the Milky Way center for some great shots! Some of you probably already know this but I have met at least 2 Pixel owners who did not know this was a thing.
