Flexbox. It's finally almost here. I cannot tell you how long I've waited for this to be supported by default in all of these browsers... as soon as Safari 7 is released, us developer sites will actually be able to make the switch. I honestly think wrangling the hacky current layout solutions is 25% or more of my time spent with CSS on a project, so hopefully we'll be able to build things much more quickly.

Happy day.
