I would LOVE to see some integration with Google Admin to pull devices. We have our Chromebooks enrolled into a Google domain, where they are stored. MAC address, serials and such.
There HAS to be a way to pull that inventory, there is a Google sheets add-on that puts the info into a sheet:

Right now we have to manually enter Chromebook, this would be a lifesaver. Also, the names of the Chromebook is in the "notes" field of Google Admin, so field mapping would be needed.
