With these changes some Particle Settings look the same as they look in the Blender timeline.

Current features

General:

• random scale
• scale over time using Color Ramp textures (only one texture and with linear interpolation)
• smooth ending/stop for non-loops
• modified pause and resume methods
• added start and stop methods
• fixed particle's random lifetime

Rotations:

• Orientation Axis: None, Object X, Object Y, Object Z, Velocity / Hair
• Randomize
• Phase
• Randomize Phase

Armory Props:

• Auto Start
• Is Unique

Planned for a new PR

General:

• animation data (animated objects)
• smooth start/stop on loops

Rotations:

• Orientation Axis: Global X, Global Y, Global Z, Velocity / Hair (velocity change alignment improvement)
• Angular Velocity (I need to take a closer look at this)

Blend Textures:

• accept multiple textures
• velocity over time

Color Ramp interpolations:

• Constant
• B-Spline
• Cardinal
• Ease

This list may change over time.

Important notes:

• in order to see the Particle System with more accuracy you need to set Particles > Velocity > Normal to 0 since ParticleSettings.normal_factor is not supported, and Blender has its default value as 1
• Velocity / Hair orientation axis needs more work, as it looks a bit flattened when the velocity direction changes over time
