Explain the problem as you see it
When modifying live queries inside a Supertag, all instances using the Supertag keep the old query definition active. You have to delete the child live queries in any node using the Supertag in order for the new query definitions to apply.
Why is this a problem for you?
Because it requires manual intervention to reflect the new live query definitions.
Suggest a solution
I propose a CMD-K option be created to force re-creating Supertag live queries definitions to all matching tagged nodes.
