This function would make it easier to see the user's view of the portal, no matter what OS or version. This could be implemented for instance as follows: From Admin-console, select Portal (or Mimic OS/version) with choice of OS: Default (i.e. same OS as that of the admin user) macOS (and version) Windows (and version/variant) etc. When in Portal, show Admin that Portal is in OS simulation mode, with OS/version/variant (header of browser/top of portal windows) And of course instruct the portal that this is the OS running so that the admin can see what apps are available, try to launch downloads, run on servers etc. (Ideally) block and inform the Admin if trying to launch apps from non-compliant OSes. Return to Admin to exit this mode
