It looks absolutely terrible having addon icons crammed into the same bar as everything else. What's the problem with the addon bar? There's even less view pane area now because the top area is so large.

The active tab curve is feminine, not in a good way, but I can live with it.

It does feel faster though, maybe they broke some addons that were slowing it down. Time will tell.

You can add another bar in the customize menu and put add-ons on that bar, if you prefer!

How do you add a bar or spacing or separators?

I believe you can't using the Customize UI, but for a hacky solution you could add spaces in bookmark titles, like this: http://cl.ly/image/2Q2b3L3c061a
