Mac users, this is really worth checking out. As you work on local projects, you have your HTML and CSS open in your text editor of choice, and the web page open in a browser. With LiveReload, as soon as you save files the changes appear in the browser (with CSS, it doesn't even need to reload the page). It also works with all the popular preprocessors and instantly compiles as you save. Might just change the way you work. I have a feeling it's going to change mine.
