Once a cell has been placed in a file, it is impossible to know where the cell came from. It would be good to have an option to display path for its cell library.
In some of my clients they have many cell libraries ranging across either organization or projects. Not knowing where the cell came from is a huge issue.
This would be useful when we need to edit or replace the cell.
As a workaround, I have bene using the add link option to each cell but this is time consuming and not everyone does it.

Would not be backwards implemented but for future versions could add item with cell library name. Unfortunately any custom tools may still place cells without such attribute.
