If I setup a new tenant for a customer right now. I make a lot of screenshots from the Admin Center to document the settings. Customers will make changes to this settings after I leave them alone ;-)
There are many Powershell Commandlets to get this settings and i save the Objects and Properties as XML Export or CSV. It would be a great feature if i could create a professional documentation for the customer and can compare this settings like on the onpremise Environements.
