Hi,
There is "Grouping Nodes" section at Edit Resource on All Node Resources. In NPM 11.5+, custom properties for group can be use. So, maybe if there is "Grouping Containers/Groups" levels at "All Groups", it can be more useful.
VERY GOOD IDEA +1
Great IDEA.
Infact I am currently struggling with some grouping issue. I which i can even get someone to help me out.
