Designer Work Tools 2013

I can already complaiine that none of the tools for live CSS editing, support SASS or LESS  (or other pre processor).

But they speed up your life so much we cannot complaine longer.

Colorpicker

What a waste Filezilla Colorpicker it copy just the color hexe code that are wrote in the css code

Colorzilla

Not only the best colorpicker on add ons market but also a precious tool for gradient generator!
Colorzilla pick also the value color from images, jpg… converting in webstandard Hex format.
If I can say something the only bad thing will be to have another standalone on the tollbar of my browser.
