Who's using the action button?

Interesting reddit thread on how people are using the new action button
introduced with the iphone 15.

Some really innovative uses but surprising amount of people who've
forgotten about it or have simply kept it as the default. I find it funny
how many have set it to the camera. Was there really a need for a *third*
quick way to access the camera?

I do like the option of setting up a menu of quick use items.

Many rue the loss of the physical switch, however.
