It would be nice to create rules or filters for folders to auto-populate devices within the folders. A lot of times customers have many locations, and being able to auto-populate devices under a specific folder would be a welcome change. Some Criteria idea's that would be helpful for my team:

Subnet Range
Device Type
WAN IP Address (The most useful for my team)
Device Type (Server, Workstation)
Device OS
CPU Type
Hardware Vendor

In addition, allowing IT Automations and reports to run against Customer folders would would solve a lot of requests.

Integration with IT Glue to sync over the folder names as a location would be icing on the cake.
