   I'm definitely open to ideas on improving the readability. We could split it 
off into its own () after min,med,max for instance. 
   
   I don't agree with your complaint that we are exposing internal details, 
that is all the UI does.  Its for the user, spark dev, spark support people to 
be able to see the details and debug it as necessary.
   The mapping of SQL operations to stages right now is terrible. This helps 
some as helps with the exec node to stage it ran in mapping, it will also help 
you debug issues where some task took much longer then others (max value). You 
can a lot more easily pinpoint that task.
   
   Another idea we could look at would be adding a radio button to disable it 
by default and then have it show up. I'm not sure how hard that would be but 
something we could investigate.
