I used group folders a while back. However because of the release cycle and issues with missing updates for group folders app, I found it much more powerfull to use a serviceaccount user called something meaningfull (Eg: Shares) in which I created a folder I shared with Admin group with full rights. Then as Admin I creates sub folders in that one shared folder, where I shares those subfolders with dedicated groups, hence I basically replicated Group Folders app behavior, using all core native functioanlity, guaranteed to work with any NC version upgrade.
Moving all files and folders from the group folders, was actually not that hard either.
