I was looking forward to a technical talk on WP’s REST API after lunch, but the presenter had to cancel last-minute. Cyndie Shaffstall was apparently asked to step in late the night before, but it was clear from the outset she was ready to deliver a ton of useful information. I gave up on fancy notes for this one, having an urge to get down as much as I could. This is all great stuff. The one weird trick I picked up on was putting arrows in your buttons—Works Magically Every Time!™
Notes went on for two pages with this one.
