I made a helper (boolean_input) using the UI but never referenced it, then realized I named it incorrectly. It is not showing as editable in the Helpers screen. I just want to delete it since I had a different one already. Now the names are confusing, and I might pick the wrong one, so I'd prefer to delete, but would settle for renaming (deprecated) or something like that.
Please tell me that we don't end up with a graveyard of mistakes that can never be removed from HA. I can't rename, I can't delete, I can't even add a note to say it should be ignored.
Not in a yaml file I can find.
