i enjoy to use this Program
nice ext
I'm revisiting this after having tried it a long time ago. The separate window is a huge improvement, and the preprocessor support is terrific.
Awesome extension! Improved my development efficiency
While there are other realtime CSS editors available... this one is by far my favorite. Not only is this a GREAT tool for writing, editing, beautifying/minifying CSS, but it also supports persistent site-by-site CSS customizations as well! Additionally, the developers are very active in its continued development and responsive to good feature requests!
This is very use full if you want customize view.
A bit more modern look could add up, but all in all, it's a great little exension!
a great tool. if you add the convert css to less part, it's even better. Thank you publisher
The buttons in the top-right bar are buggy and sometimes are invisible, though they can be clicked. The style pinner shows a notification on page load which is annoying. It's better to change the icon of the extension to indicate active style injection (see Stylus). Otherwise, great extension!
nice
