You can debug and change SASS code directly from Chromes developers tools. I am not going to talk about how to set it up as there are plenty of guides out there how to do that. It is just an amazing news for me and I hope to spread the word. It requires SASS 3.3.0 or up also the SASS support is not enabled by default, which makes since because 99.999...% of chrome users won't ever need it. Sources panel editing capabilities are limited, it doesn't have the awesome tools of sublime for an example. Never the less it supports saving .scss file.
