We have made a lot of progress this week. Admins have helped us uncover a lot of bugs in the new UI and we have squashed every one of them! We are on track to roll out the beta to the rest of the users next week.
One thing we need to make Admins aware of is how you can brand your header. This is going to take some planning and work on your part. We will be glad to assist. See this help article.
Keep in mind that we plan to continue to allow access to both the old and new UI through a toggle. We will do this for several months until everyone is really comfortable with the new UI. Meanwhile, we will be working on a few major projects we have been putting off which are unrelated to the new UI, so there won’t be many changes in the UI other than bug fixes.
Since the new UI is still in beta, please address your questions to your Admin who will forward them to us if necessary.
