Here you go.
I came across this whilst looking for daring fireballs LIVERELOAD plugin, which I use for free on my old 32bit Snow Leopard (mac) installation.
THIS
it is a browser plugin for Chrome (damn! not firefox) and auto installs in SublimeText - and can be used in Atom too. I dont think it auto installs there though. I have just forgotten!
might be a handy tool for someone. I like the idea
ps, oh yeah, its new to me. you might already know about it. If not, then HEY! its now new to you too and the heading is apt
