interesting! I'm seeing them grouped in the middle. It's a tricky layout, using d3.js's circle packing algorithm, then recursively using a force layout to relax each folder's contents.
In the part that says "direct link to your own repository" you can add a link icon for people (like me) that doesn't read all the text. (I was going to suggest that as a feature, but looking again I found it.)
It would be nice that if I have chosen a repo above, the link includes that repo instead of the default one.
