The minimal look feels very refreshing, and yet it's not disorienting like many minimal web git UIs are in my experience; I actually feel like I know how to navigate this thing. Site feels very snappy too, especially with those instantly loading file previews when you hover. Congrats!
It seems like the site is currently getting hugged so I can't look but I'm glad someone is trying to achieve a more minimalistic take on the UX of a software forge. It seems like an area with good room for improvement.
