SUMMARY Not that the "classic" theme is better than the new one, but still... changing doesn't work. STEPS TO REPRODUCE 1. Go to preferences 2. General preferences 3. Select "Classic" under General appearance -> skin 4. Save settings OBSERVED RESULT Dusk theme is still used EXPECTED RESULT Classic theme is used. Or whatever dark theme is added in the future.
The Dusk and Classic themes of the past have been replaced by the new one. So meaning of "Classic" has changed. Currently, the way it is set up is: Classic theme: Monospace font in comments section Dusk theme: Sans Serif font in comments section Everything else is same between the two themes. The old theme is no longer an available option. We've to work with the constraint of just changing the CSS without touching anything else, so this is just a technical limitation we have to work with.
