It would be great if agol (or portal) administrators could impersonate a user to see what user experience they have and confirm they have the right permissions and access. We seem to spend a bit of time following trails of permissions for maps, layer, web app, etc.. to make sure a particular user can access content correctly. This capability would hopefully make this process only take only take a few seconds to sort out rather than going back and forth with the end user confirming they have the right access. Other systems have this capability such as service now. The capability to impersonate could be a permission based option in itself eg allow user to impersonate that administrators could set. If concerns are raised over editing content or data while impersonating maybe the edit tracking could be highlighted with the impersonate details eg last edited by: adminaccount (impersonating otheruser) or editing could just be disabled while impersonating.
