Increase the number of things that can be modified at country management level.
For example each of the road types creation, could be limited to an editor of a certain level.
Similarly, the walking tracks, railroads, cameras, etc.

I would love to see self managed countries have the ability to restrict certain road type creations to editor rank level. In the UK we have a common, recurring issue whereby new editors mass-add loads of walkways/footpaths that add no value at all to the map. I'd love to see these restricted to a higher rank.
