Absolutely wonderful! Thank you for making this. Truly an outstanding extension. It helps me use my own scripts without having to pack them as extensions.
I love it, why i only see this now.
great work!! please add syn with google extensions.
Works great, the editor is good as well. Adding support for sync with google drive would be nice, so I can have the same thing on multiple browser. Can you please add support for LESS or SASS?
Лучшее расширение в этой области. Искал долго среди подобных программ. Даже своё расширение писал (неудачно). У всех остальных или интерфейс неудобный, или реализация не очень. Тут же есть всё что нужно. Автору огромное спасибо.
Fantastic! I love it!
非常实用，超级棒
Лучшее дополнение!
Awesome <3
its Great ! if use correctly
