I've used multiple cursors with Emacs and Vim. It's really nice, but I kind of still don't need that feature.

For beauty, I really love my Solarized desktop. It's functional, the colours are nice and I know exactly where is my editor, my browser and my test terminals.

So, coming from the Mac OS X world, I started to see the real beauty of my engineering desktop. And of course all the configs are in Github.
