There’s been chatter about The Moylan Arrow recently – the indicator showing which side of the car fuel intake is on. Which made me think: What would be the equivalent of this in software?
My best guess is iOS offering to fill the one-time code from a recent SMS:
- everyone benefits from it
- happens all the time
- solves a real little (but not too little) frustration
- right place/right time
- relatively low-tech
- once you know it’s there, you love it forever
Curious what others think!
