Wouldn’t it be a good idea to have a feature to generate automatic data backup at a specified interval in a specified folder? Maybe delete backups older than a certain age?

It might be but how difficult is it for any of us to accomplish manually? I typically do a backup monthly, plus whenever I add/remove a playlist. I will always backup before app updates. In that way, I retain the option to drop back a version and rebuild the app. My backups are stored in Downloader files, and always carry a time/date stamp, so it's simple to ID the oldest. 👍

Sounds like a great idea
