I most commonly want to look/render a single subgraph.
A failed workunit has reported an error in a subgraph/activity, or seen on heatmap or Timings section and want to jump to it.
I don't think there's anyway to go directly to just that subgraph.
If you click on a Timings subgraph or a heatmap subgraph it renders it in the context of the graph.
That means it takes a lot longer than desirable and in some cases when graph is huge it crashes the graph control.
