Hey all, I thought this might be useful for anyone who uses preprocessing tools (like the excellent CodeKit: http://incident57.com/codekit). I came across Prepros the other day: http://alphapixels.com/prepros/
I always used CodeKit up until recently. However, it's only available for mac and recently I have had to dip my toes into the waters of the dark side again with a PC laptop I needed something that would work cross-platform (Prepros works across PC, Mac and Linux).
From what I have seen so far Prepros is growing quickly, free, supports nearly every type compiled CSS, has real time refreshes and works across platforms.
