I had already tried it but was wondering if anyone had rolled it out to users and with what results.
I tested it in our development environment and my team liked it. When we upgraded our Prod environment I enabled it for one site and have got positive feedback from a handful of users. They like that it works more like folders on a computer. One change that took some time to notice is that the term "Explore" has slipped in and mention of "Project" is hidden more. The word "Project" for what is actually a folder has been always been unintuitive for users. I try to refer to them as "project folders" when talking to new users who tend to think of their workbook as a project.
