Particle Viewer is missing some features, such as:
1.) Being able to properly see per Operator Data
2.) Two separate reset buttons (Partial Reset vs full Replay - currently only Full Replay exists, PET has both)
3.) Live particle data like amount of particles, etc.
4.) No enable / disable toggle per parameter (could be interesting)
5.) Control Points not shown or editable / movable
6.) No Child Systems (or parent for navigation) visible
7.) No live pause, frame stepping, etc.
