    preferences: save an extra 24px in width
    
    Currently we can't use the programming languages side-by-side
    layout on screens with 1280 width. While that is less than
    ideal, it could be common today with 2x rendering by the
    compositor/gtk. So we need to support it to some degree.
    
    This gets us down to 1324, so we still need to shave off another
    44 pixels from the min-width.
