I have several dashboards and many views using custom:auto-entities and to keep the less useful stuff from appearing, this appears littered in a few dozen places. More often every time I update this list I have to go to all those places to change it.
One thing it has impacted, I think, is documentation. While there’s still yaml configuration info in them, it’s far less complete now. They (the infamous “they”) appear to be deferring to GUI dialogs to specify details like layout and doing a more poor job of describing the syntax. I frequently set up a fake dashboard in the GUI and make a setting to look at the underlying yaml.
Always like to see examples of clever approaches, but the in-file yaml is not my question, I am asking about UI dashboards (which have YAML underneath).
