YES! and ability of having objects as particles too

Yes, this would be absolutely wonderful. The particle system is hideously limited, even in comparison to other metaverse platforms. I would also suggest an addendum to ribbon particles, which are world-aligned biplanar (intersecting, perpendicular) ribbons, thereby eliminating having to double up on ribbons. By having them world-aligned, in addition, it better represents flexible objects between two points: ropes, tubes, hoses, laser beams, and so on. Especially when combined with the previously mentioned flicker elimination, it would make particles better and more useful as a whole.

Also one for particles review : when working with a ribbon mask, the particle begins at the source exactly by gradually 'growing' the first particle then when at full size it moves off up the line. But where it ends at the target, it is only ever the size of one full particle, then vanishes, so what you get is constant flickering at the target end as whole particles die.

The current workaround is to have another emitter at the target end working in the opposite direction to hide the flicker, but it is rather wasteful on the number of rendered particles in the viewer, being double what it really needs to be.

Yes please. I'd also like to add the ability to set the rotational facing of the particles per axis (including random rotations per particle). The total overhaul of particles as mentioned above plus this would make particles a MUCH more viable tool to work with and could create some incredibly interesting effects.
