Better counter instance selection experience
When looking at a graph with many counter instances, it's helpful to select an instance and highlight it in the graph. However, deselecting it or going back to all instances being "highlighted" is difficult. In a live view, the selected instance moves around the instance legend making it difficult to deselect.
I think the selected instance(s) should be pinned at the top/beginning of the instance legend being sorted by name or value. If the selected instance is deselected it should go back to being sorted the same was as the other deselected instances.
