Who remembers Harpoon III's formation editor? IMO that's the bar to shoot for.
Defined arcs at defined distances, and it's super easy to drag a patrol zone to a different place. ALSO it has threat axises, a very useful feature to quickly move many units to fleet defense positions in one go.
Global Conflict Blue 2 attempted a similar thing, but directly on the UI map. The arcs/zones are a bit hard to properly grab tho. Too bad development stopped on that. I'm pretty sure CMANO killed it off cuz the devs just bought that LOL.

CMO could take that and run with it. It would make managing formations MUCH quicker, easier, and more intuitive. And adding threat axises would be a great UX boon.
No defining a bunch of reference points, and then having to individually move each to change the parameters of the patrol zone.
Here's a very good video that does a comparison between formation editors. Including CMANO as of 8 years ago. It doesn't appear much has changed in that time regarding formations in CMO.
Harpoon III starts ~33:10, CMANO is immediately prior.
