Very nice, but what I'd personally rather have is a two-pane navigator: explore the tree in the left pane, see file contents in the right, a la NERDtree, eclipse, and other IDEs.

I find the animation to be rather annoying.

It looks like the sliding transition may also mask network latency; clever.

I guess this is a good place to ask, but does anyone know why GitHub opted not to list the file size in the file viewer? Whenever I browse other peoples' code I always want to glance at file sizes to see which files I should peruse first.

I would love it if this widget eager-loaded the directory structure for a couple levels (doesn't even need to load the commit data) so that it made the navigation to a specific file/folder even faster.

And thankfully they didn't screw up the ability to open links in a new tab.

Great! I've been looking forward to this feature for a long time.

I wonder if this is better than sammy.js

A sliding UI is worth #2 HN spot? Wow.
