Make toolbox top a little more like everyone else's. 

The use of PR to mean PSR rather than PR was confusing, so let's just
use PR and NI the same way everyone else does.

Also remove bogus blank lines and unnecessary delays (both before first
showing anything and after having shown the final iteration).
