    Кавашировские расширения для Google+


Распространяется по лицензии WTFPL.
Внимание! Chromium-подобные браузеры (Chrome, Vivaldi, Opera, ...) на 2016.12.22 не поддерживают необходимые для работы скрипта HTML5 контекстные меню. Для включения эксперементальной поддержки необходимо включить ContextMenu в Blink. Это можно сделать флагом запуска --enable-blink-features=ContextMenu. При этом возможны проблемы.
Для нового интерфейса. Добавляет контекстные меню:

(На youtube-видео) "Открыть видео на YouTube", т.к. на данный невозможно открыть видео в отдельном окне не открыв видео в текущем.
(На youtube-видео) ... или скопировать ☝️ ссылку
Открыть полноразмерную (/s0/) версию изображения (или превью, в случае видео).
... или скопировать ☝️ ссылку (на превью, в случае видео).
Искать картинку в IQDB, при этом не должно возникать ошибок из-за проблем с WebP.
Искать картинку в SauceNao.
Искать картинку в Google Images.

Принимаются реквесты, возможно дальнейшее расширение функций.
