[REL] Speedometer
It says v0.1, but I may or may not make a second version.
It can show either the fastest (the built-in speedometer does this) part, slowest part, average of all the parts' speeds, or a specific part.
Should be easy enough to manipulate; feel free to use it in something, but if you do, I'd like credit 'cuz this was a pain. Lolfail.
