Visualize the scope level to which an operator is applied on
|Reported by:||abeham||Owned by:||mkommend|
To make the operator graph more friendly to users we could visualize the scope level to which an operator is applied on. For any operator the level only depends on the number of SubScopeOperators that appear in the path before. So the graph will need to be traversed backwards from the selected operator to the initial operator and a tree view needs to be created with highlighted nodes where the operator is applied on.
