Find orphaned entries of customized entities

[schneekluth]

I started homeassistant on version 0.14 and since then my config has undergone many changes over the years. Spook helped a lot in finding ophaned entries in my dashboards which led me to the idea whether it's possible to also find orphaned entries in manually customized entities?

I have used the customization options to assign friendly names, icons, etc. and lots of entries simply do not exist anymore in my latest config. Would spook be able to detect these customized entries if they are no longer present?
