Emitter:

• "Particle End Scale Variation" is too long title for a property, it get's truncated always.

Particle:

• Valid values for colorVariation property are in range [0,1.0], but UI controls allow unbounded values with step of 1.

Model Particle:

• InstanceTable property is read-only, as it always points to the internal instance table of the ModelParticle, so it shouldn't have field in property editor.

Attractor:

• Properties are missing NodeSection
  • Unlike other affectors, Attractor's node position is meaningful, so node properties should be present in the property sheet.

Wander:

• Pace properties should have smaller step, the default step of 1 is way too large for practical values.
  • 0.01 is probably the proper step size.

Gravity, Point Rotator, Wander:

• Technically these are also nodes, so they should have node properties present on the property sheets.
  • However, their node properties have zero impact on how these affectors function, so it might make sense to keep them hidden, even if it is technically incorrect.
