I am creating a lot of helpers to configure my Node Red based automations. Sometimes I rip something out and forget to clean up by deleting the helpers that were used by that automation. It would be nice to have some way to see what helpers are used (not only within HA itself, but Node Red as well) and which ones are unused. A proxy showing the last time one was used might help if it is not possible to reliably determine whether a helper is in use somewhere or not.
