Actually, a parts counter does
exist, though it is offsite...http://fc.therisenrealm.com/tools/hap-calculator
Comes in handy when scoring competition entries with many pieces. It counts and values pieces and helps score designs as being green or brown. Since it is only reviewing the static (unrun) design, there are also tick boxes to include Champ, Clean and Boomerang values into a score. Haphazard turned me on to this... "Awesome job" to whoever designed it!
