1. Firstly, bookmark folders don't appear in the smart address field or new tab view. They appear on iOS - so hopefully they're going to be added soon? At the moment I've had to re-enable the bookmark toolbar due to the lack of bookmark folder support in the address field and new tab view. 2. Secondly, Reader view is kinda ugly and still set out in Georgia. Hopefully this is not by design and they are going to introduce Helvetica Neue and a prettier Reader view for Mac that mirrors iOS. 3. And finally, the Frequently Visited view on the new tab view is kinda annoying and can't be disabled/emptied/hidden without clearing your whole history. Hope all these things are going to be sorted by the end because the new UI with the compact top toolbar is awesome. The unfortunate thing is though that they could easily be by design and not slated for a fix!
