Initial impressions: I like it a lot. Feels much more at home on iOS 11 than iOS 10 though. The fonts are matching the brutalist approach that iOS 11 is being patterned toward.

The quick swipe (or profile icon tap) to access specific profile sections is nice. I can now access my lists more quickly, and overall I see a lot of good things in this new layout.

I wish that the creation of new tweets was more accessible. I feel a FAB, or central "new tweet" button at the bottom would make it easier to tweet quickly. I'm still a big supporter of one-handed phone usage. Another and more viable option would be a persistent input field at the bottom to tweet from.

I like the subtle animations throughout. Nice subtle smooth visuals.
