In bug 134564 we introduced treelines to easily see what attributes below to a certain style. But in case of overridden attributes it might be helpful to show the inheritance.
The attached example uses a PS in red, CS in green, and DF in blue (which is the effective color). Linking them might help to understand the situation.
To avoid overlapping connector lines we could show this only when a node is selected.
As an intermediate step, somewhat simpler would be to implement simple highlighting of related entries when one clicks on one of them (so clicking one of CharColor would highlight all the other CharColor entries).
