I think I'm as interested in it from a pure "button that's always with me" perspective. I already have my original Amazfit Bip watch configured to send a "track back" signal to Snipd via Gadgetbridge to snip podcast notes while I'm driving or washing dishes or whatever. And I've configured a basic Bluetooth remote camera shutter to turn pages forward and backward in KOReader on my Onyx Boox Poke 2 Color so I can read it on a stand while riding a stationary bike under my desk.

In other words, I am apparently exactly the kind of weirdo who would use the heck out of something like this!
