The current triangle has the disadvantage of being to small to show color and, moreover, can easily be mistaken for the arrow symbol that expands/collapses a group hierarchy.
Material design icons provide a full circle but this one is slightly to large.
@halirutan may I assign you this issue since you are our expert in creating custom font-based icons (e.g. a smaller circle or whatever you think is suitable)?
