Лучшее расширение из тех, что пробовал на сегодняшний день. Да, не спорю, есть что хотелось бы добавить, но у каждого свои желания и всем не угодишь)))
Desde me lo descubrí no puedo vivir sin él, una auténtica maravilla
Essential for front-end devs. After using this you may wonder how you ever managed without it!
loved the first ONE MINUTE of this extension great app!
Very useful.
Действительно лучшее, но жаль что нет синхронизации или хотябы экспорта! ----------------------------------------------------------------------------------------------------------- Really the best, but it is a pity that there is no synchronization or at least export!
You are a genius! This is saving me sooooooo much time its untrue. Thanks muchly
BIG BUG ！！！！ when set div { background-color:red } the background color of the edit view been changed too. So every elements in the edit view should set !important to all styles;
Absolutely love this extension, I use it every day. Nice work guys!
A great plugin, I love you 3000!
