I would love to use the new UI everywhere with the exception of the projects page, too much whitespace and bad alignments and also all the right column is wasted for info that previously you could see just in one row.
Who is going to create a chrome extension to bring back the old Github UI?
Ugh, the amount of space wasted on a wider screen is borderline criminal. Whitespace everywhere!! And the tabs above being left-aligned with the main repo being centered below is just maddening. It's a real eyesore - please allow us to revert to the original UI if possible!
