LiveReload is an app that does exactly what it sounds like: Apply CSS edits and image changes in your web work live; no annoying manual reloads of your web page any more. I while ago I gave an earlier version of this tool a whirl, but it was hard to set up; lots of command line calls and Ruby gems.
Not anymore – one $10 Mac App Store app and a simple Chrome extension and I’m ready for business. I’m a bit embarrassed that I didn’t discover and start using this tool earlier; I’d highly recommend checking it out if you’re a web developer.
