Livereload is one the coolest things to happen to frontend development in the last little while, and actually it can really speed up your work. Basically it re-loads your CSS (and Javascript some of the time) automatically as you make changes. You don't have to make a change and then switch to your browser and manually reload the entire page, change 'notifications' are pushed to the browser where they will trigger that single changed file...
