Thanks for helping to move this forward, Louie! My worry with this approach is that all of the line numbers are redrawn upon scrolling, which would be likely to make scrolling less smooth, especially on low-end hardware (where IDLE is relatively often used). The alternate implementation approach we are pursuing in #17535 uses a second text widget, whose scrolling is synced to the main text widget, and whose contents are only updated when the number of lines in the main text widget changes.
