I was frustrated with how bad a signal of progress through a big PR "Files viewed" was, so I made a "Lines viewed" indicator to complement it.Designed to look like a stock Github UI element - even respects light/dark theme. Runs fully locally, no API calls.Splits insertions and deletions by default, but you can also merge them into a single "lines" figure in the settings.
