I wanted to suggest that the nodes catch and status get another node selection grouping. Currently you can choose between all nodes and selected nodes. I would find it useful if all nodes of the group were also available for selection. If this is selected, only nodes from the same group and possibly subgroups are reacted to.
I would do the development. First local tests were positive.
Can I make the pull request then, or is there something I need to consider first. The website says something about signing a CLA and a discussion in the community?
