After the new experience for document libraries, site contents and SharePoint sites the lists are next. Hereby the notification in the message center:
Updated Feature: Modern SharePoint Lists
We’re making some changes to lists in SharePoint. Modern lists offer many UI enhancements such as inline creation of custom views and columns; improved mobile support; PowerApps and Flow integration; and the information panel. We’ve replaced the Ribbon with a clean, responsive command bar. We’re going to start rolling out modern lists for First Release Users in early August, with First Release Tenants and Production rings following.
How does this affect me?
The modern list will be the default experience for all lists except as noted below. Some customizations are not yet supported in the modern experience, and if we detect such a customization we will automatically redirect users to the classic experience.
What do I need to do to prepare for this change?
Administrators may choose to disable the modern lists experience on a per list, per site, or tenant wide basis, using the same control previously offered for modern document libraries. If modern experiences are enabled, any SharePoint user will be able to preview the modern lists experience, regardless of First Release or Production rollout schedule, starting next week. Please watch the Message Center for specifics when preview becomes available. Please click Additional Information to learn more.
