The pagination of repos is kind of annoying compared to being able to quickly Cmd+F on a page to find a repo. They added their own search box but it feels slower than the browser-based one and also doesn't do infix searching (I type "www" expecting to find my "closeio-www" repo but it doesn't show up unless I type "closeio-w".), although hopefully that will be fixed.
Why is the organization name in the actual repos lowercase?
For example, https://github.com/eBay eBay is the org name but the actual repos are listed in lowercase, like "ebay / restsuperman" (which doesn't matter for the website but does matter for the git urls)
I'd with the design would be more dense, it's a nice design and I understand that designers did it deliberately because they know whitespace does matters, but when it comes to web sites like Github I think the most important thing is functionality and not the cute and modern look. With the old design on my 13 inch MBP I could see 6 repos with the new design - only 5
