Although there is a "Go to line" option in the internal file editor, it is a little bit tedious to use this each time, so would be nice to be able to have line numbers as an option in the Preferences.
Fair question. I think some of us want it because the internal editor is so lightweight, convenient and easy to use compared to editors that have line numbering.
Does the addition of a line numbering feature to the native editor have a downside? Perhaps it is too challenging to do, it adds unnecessary complexity, or violates a esthetic?
