Funny. When I first switched from iPhone to Android, I downloaded a podcast player app one day. It has about 9000 knobs, levers and other controls to customize everything you could possibly imagine. Years later, I still have no idea what most of them do. But a few of them have been incredibly useful over the years. Advanced, complicated options that I had to Google or read Reddit threads to understand. Things that I could have survived without, are probably not used by very many people, but for those that do use those features, life is better with them.
Anyway, as soon as I had a cursory glance around the app, I immediately purchased the paid/pro version, not yet even knowing if I'd ever use the app again (at the time I didn't know when I'd even have time to listen to podcasts). These were my people.
