Happy to help!

card: type: todo-list entity: todo.low_batteries title: Low Batteries

It’s a built-in card, as of 2023.11. On my instance, it’s listed below the Vertical Stack card.

You’re welcome. Pretty cool features with to-do lists now, and the conditional card got some nice updates as well.

Per the release notes for 2023.11, Shopping Lists have become To-Do Lists and the card has been renamed to To-Do List Card.

I use Reeder as well, with my feeds coming from Feedbin. Reeder has an option to use iCloud to hold & sync feeds across your devices, but I haven’t had good luck with that.
