Find dependancy Component(s) & Screen(s) per Column

Hi, it has for sure already been required but I don’t find where.
Use case: yesterday, @Jeff_Hager had the “bad idea” to solve one of my issue; it led me to delete a misfunctioning Relation-Lookup… one of the key one of my app. I spent hours to review each of my hundreds of components to check whether or not they depend on the Lookup…

I get very sad when I delete things that are needed
