Инструмент очень простой и полезный! Свои функции выполняет отлично. Хотелось бы иметь возможность делиться своими скриптами для конкретного сайта, например экспортировать его в json отправить колеге, а он его экспортирует у себя.
Not working for me. Tried removing logo on youtube and it doesn't work. If dev fixes issue i will remove this review. P.s. my code: #logo { display:none; } & it worked on another plugin but that one is only a live viewer so maybe it's an issue with this extension.
Very well made extension. The built-in editor is super nice to use.
It's GREAT! But I wish the options page was wider, especially the sites list
It's a Great extension. The only problem is CSS styles won't work for iframes in page. However, GM_addStyle function in TamperMonkey works well. Thanks!
Простенький. Работает как положено. Огонь, короче! Комьюнити можно собрать и делиться скриптами под сайты.
There are four requirements. ① I don't see the error on both the latest version of Chrome and the latest version of Edge. The ability to spit out errors was really helpful, Therefore, please implement the error detection function of the 「JavaScript」 editor in the latest version of Chrome & Edge. ② Some scripts do not work with Tampermonkey or Greasemonkey injection, so we would appreciate it if you could release it as an add-on for the Firefox version. I'm also fascinated by the fact that it's lighter than these extensions. ③ I also find the "use CSS color selection tool" generator popup like "Stylus" useful. Please consider. https://lh3.googleusercontent.com/mEMaV-MebApPq01XGO1sSarURMPheO8g7nSW3wnMVlzRKA4ZQSUm90E6yoza6mKEbphm9Tqht5C5brnGWo3qanqbFg=w640-h400-e365-rj-sc0x00ffffff ④ Also, it would be great if we could use regular expression URLs in CSS. example: https?:\/\/(www\.)?google\.(com|fr|ru)\/search\?(.*)q=(?!.*(\&tbm)\=(vid|nws|bks|shop|isch)\&).*
Works! Működik! 🙏
