New feature: Introducing a new file experience for groups in Outlook on the web

So with this upgrade it looks like it has removed the ability to stop inherit rights on a folder and then to remove any of the default groups (Share Members & Share Visitors)? This was a nice feature as we used it to replace network drives on local servers. Occasionally we would have a folder in the group that we needed to make private by removing the members and visitors and then just added the few users that needed access.
