Text panel - show row I'm editing

When I go to edit a text panel in grasshopper, the row index disappears. How can I keep showing this so I know which row I’m editing?

If you are referring to the panel editor, the indexes are not displayed there.

That’s what I thought. I used this http://textmechanic.com/text-tools/numeration-tools/generate-list-numbers/
to generate a list of numbers so I can track as I edit through. Not sure how else to do it.
