Is there a way to sort rules in the plugin dropdown?

I know you can sort rules in the extension settings, but I have multiple rules for a website and I would like to sort them in a specific way - is this possible?

Iframes

Написал код (рабочий), тыкнул снизу галочку "Все фреймы", захожу на сайт, код запускается только на 0 фрейме, не пойму как сделать что-бы на всех/только_нужном йфрейме работал код, в вики мало об этом инфы

Снять ограничение на 120 хромиум

Привет, а можно снять ограничение на 120 хромиум? ну или хотябы понизить до 118. Я просто использую цент браузер, из за этого все еще сижу на 2 версии расширения, но хотелось бы 3-ю опробовать.

JavaScript not working with DOMContentLoaded

Hi, I had some JavaScript added and it was working fine before but after updating the extension it doesn't work anymore and I get this warning. "The `DOMContentLoaded` event will not fire, enable the “run on start” mode" Is this option in extension or how could I fix it?

Shared scripts report redefinitions

I don't know what's changed in the latest version, but I now see that if I use multiple scripts with a shared dependency (modules), these now declare redefinitions (Identifier '...' has already been declared) when they didn't previously. Since I don't have a way to know if a shared module has been loaded before, this is causing problems which I'll need to solve by testing for redeclarations myself. Is this intentional?
