Sticky stage graph and current executing step when following along in karaoke

Currently when following along in "Karaoke" mode the stage graph and step header scrolls out of view when the log gets long. 

It may be worth considering changing the behavior to show at least some context of the current stage graph (if not the whole graph) and perhaps the step header (see attached) at all times. 

This would reduce the need for people to scroll up, stopping (often unknowingly) the following along from log, but still let them see the context and log at the same time.
