I use templates a fair bit to generate nice custom cards. It’d be great if it was possible to configure templates much more easily than currently - either I have to build a custom sensor in YAML or populate a markdown UI card. I’d love to be able to custom format an entity’s display using a simple template directly in the lovelace, rather than from a separate card.
There’s a card for that. I don’t remember its name, but it works for any card.
