Maintenance Window tab in device properties
In Assets and Compliance -> Devices -> (right click any device) -> Properties
There are currently 3 tabs, General, Deployments, Variables. Since a device can be part of several different collections and maintenance windows are applied on the collection level it would be nice to quickly see what maintenance windows are assigned to a device.
Check out my Tool, it already supports this. Maybe the ConfigMgr team can steal it and add it.
It uses all native ConfigMgr APIs so it should look and feel like part of your console.

As a way to work around this limitation, our organization created a PowerShell script to get this information. Perhaps this would help with the development of this feature? Is there a way to add screenshots to this thread?
