After adding Path effect, the original path is not visible.
i think the original path should be visible when we use node tool because that is meant for editing path.
In blender, this issue is solved by having toggle that show original and when checked shows the applied effect and node positions change accordingly. if that is not possible atleast show original path either in fainted color or dashed stroke.
apart from it, the node points of path and node points of other function should have better contrast either through color or shape, the confusion occur mainly when both nodes are round.
