So here's what I suggest to the author: go to the "Issues" page for some project, and see the effect of this redesign.

From my perspective: there's now a lot of useless tabs on the top (commits/branches/releases), the repository description will either take extra space OR will disappear and the tabs are going to shift.

- Getting rid of icons: OK

- Moving description over tabs: bad

- Shuffling tabs around: bad

- Different info instead of code details: meh

- Vanity counters: OK

- Changed style/color-scheme: bike-shedding / meh

Opinionated summary: hit and miss.
