You should check out gitlab.com
GitLab's UI/UX is regressive to the point that when you visit a repo, you have to click another link just to see the damn sourcecode. It's as though they ignored every advance in source-code UX post-Sourceforge.
The stacked global and per-repo sidebars are confusing in a way that baffled me for several minutes, as well. They need a serious rethink of their UI/UX.
The main issue with GitLab right now IMO is that it's so fucking slow at times -- ike seconds per page slow...
BTW on-premises GitLab installations should be fast already
