Simplemente genial! No se puede creer que algo tan sencillo sea tan potente. Muchas gracias!
One of the extensions I use the MOST. Saves a bunch of time when developing straight in browser. I would love to see some jQuery support as well instead of deferring to the console.
Отлично, то что искал.
This plugin save my life everyday. <3
I use this plugin on a daily basis. I don't mean just once or twice in a day, I mean it makes 5 hours of work take 2 for me, and I use it constantly. A sincere hats off to the developers of this. Also, it has a great personality, if that's not anthropomorphising more than I should:p
This is by far the most useful web development chrome plugin I have ever used. EXCELLENT!
you should totally build this as a application on the play store for android web browsers and pages i think this would be a super successful product on the play store
it is a good program, just if could find site sass files and ability to change theme it will be greate
wonderful
Раньше приходилось постоянно метаться между нетворком и сайтом, теперь больше времени трачу на вёрстку. Очень полезное расширение. Как бы сказал Логвинов: "12\10!".
