Question:

- Is the layout enabled and delivered by default at part of 20B?

- Can we continue to use old layout with only enabling the UI responsive pages profiles in 20B and later? 

- Appreciate comments from users who have been using Newsfeed layout to share their experiences compared to existing layout design.

Our org user community is across Finance, Procurement and HCM. Though, the Newsfeed layout provides some features like global search, quick actions, things to do, etc. however, the subject area is listed in the horizontal view. User needs to scroll horizontally to view the module functions. Appreciate if there is a way to avoid this.
