It's a great extra but currently the inline style picker isn't working.

Stylish site never loads. Just a spinning color wheel forever. It's not Stylus's fault, but since it's an integral piece of what this add on does, it's just not that useful anymore.

Nice

Очень хорошее расширение. Любой сайт с ним преображается.

Very convenient. Somehow it took me months to figure out how to make a style apply only to the current url (click the url parts in the small popup that opens when clicking the extension). I think the UI could be simplified to make it more user friendly, but overall it's quite good.
Some of my use cases :
- add `body{background:red} ` on your production website to not confuse it with staging.
- hide the advertising line at the top of the mailbox in yandex mail
- make a touch typing website responsive and ad free

I already have an ad blocker but this lets me get that ads space back for content.
