• Horrible option interface
• A stupid menu bar above the video, it interferes, and it seems that it can not be turned off.

• Bypass regional restrictions is the best of all add-ons
• Nice improvement in commentary and volume controls

• Ужасный интерфейс настройки
• Дурацкая плашка меню над видео, мешает, и похоже не отключаемая.

• Обход региональных ограничений лучший из всех дополнений
• Неплохое улучшение комментариев и регулировки громкости

• Add categories, create, rename.
  Now all the news is in one heap.
• Ability to rename sources
  Some source titles may contain a lot of unnecessary text.
• Ability to display personalized news on the home page
• full-fledged Import / Export

All improvements are of great importance to me,
and improve basic functionality, for example developers should look at "Feedly" and other news aggregators.
