This talk, from 26 May, is an exceptionally clear, and friendly, description of Searching for British records in the new FamilySearch website by Sharon Hintze, the Director of the Family History Centre at South Kensington. I recommend it.
We are taken through the records for each of the components of the British Isles. Note that while there is apparently an entry for England in the version of the database used in the description I only see the England files under the general United Kingdom heading.
There is also a bit of a heads-up on forthcoming content under Trees from the main FamilySearch page, and a brief mention of some of the issues with the new website.
