I just miss the desktop mode link on the bottom of every page. Sure it's harder to use, and I spend most of my time in mobile view, but sometimes I just need to get shit done.

I actually sent them a support ticket about this, and this was their reply:

"I understand how the previous workflow would be useful, and we apologize for the inconvenience it has caused.

However, the good news is that the mobile team is working on releasing iOS and Android GitHub mobile applications early next year, which should resolve some of the limitations of the current mobile site."

Like really, just give me the desktop view back ffs.
