Great extension, thank you, but there is a moment that can be improved. Please, add possibility to load js/css from files, to work inside your favorite IDE and after saving it to load them in extension.
расширение крутое, но почему-то пропал сайт из списка, там уже написано куча кода, и он его применяет, где искать концы? заново что ли всё писать?
Genuinely phenomenal. Worked just like I wanted it to, right out of the box. Great stuff.
Used for CSS. Works perfectly. Thanks!
this extension does what it says on the can. it just works. great. maybe missing a way to share scripts/css, but i get it, security and all.
Лучший для меня!
Спасибо автору, CSS работает хорошо. Но почему не запускается JavaScript? Из консоли код работает, из расширения - ни чего. Chrome прикрыл возможность? Автор, ответьте плз!
Absolutely the best extension I've been looking for. Finally I can hide all those useless things I never want to see. Thank you for this perfect extension
Perfect. The auto !important is a very useful button.
