Extremely useful tool.
Perfect! But searching is missing.
Poor implementation... loads on the page you're on, meaning if it has keyboard shortcuts assigned to regular keys, you won't be able to type anything
Thanks for this addon.
Thanks. Great extension.
Muy útil, sencillo y práctico.
By far one of the best extensions you need for your work as a web designer. Just WOW!
WOW just WOW .... its the best css-editor extension that I ever used :) keep the good work.
this is a very helpful tool. I loved it since the first use, keep up the good work guys <3..
I've been looking for a replacement for Stylebot and this is almost exactly what I need! The only problem is the pop-up text that appears in the top right corner when you've set the extension to apply styles automatically. It gets kind of distracting when it appears each time you refresh or navigate to a different page. If we could get an option to disable that pop-up, this would be perfect!
