Good changes! The file activity card improvement will be useful for our teachers who will be able to see who has viewed a file. I also appreciate the effort to make the UI more consistent. A couple of questions and comments:
1. Will recommended files be the default? And how do you switch between the recommended files view and the list view? Honestly, I suspect most of our users will find the recommended view to be a distraction, but we shall see.
2. Any changes to the “Shared” view? Shared with me and by me is a bit of a mess currently, to be honest, and are at the very top of the list of issues that we hear from our users. A redesign would be very helpful. This is a part of the experience which is not consistent with OneDrive on the desktop. For instance: on the web you now have “Shared” (with files and folders shared from OneDrive) and “Shared libraries” (from SharePoint), but in file explorer you have “Company name”, which shows shared folders and libraries, but not single files, and only if you have explicitly chosen to sync them. For file explorer it would be really nice, if it just automatically showed all shared files, folders and libraries. With files on demand, disk space is not as big a worry as before. Even for those libraries, which are not allowed to sync, you could replace all files and folders with shortcuts to the web version, much like OneNote.
3. Will we ever see a foldable tree view like in file explorer? Sorry, had to ask :)
