I know you have loads to do and I dont think that your up to particles but heres what I have experienced for the todo note pad
* Only 1 particle can be placed in a scene without over writing the settings for the 1st particle.
* Sequence of files doesnt work (grayed out play animation)
* Repeat interval 0.01 displays a pause in the particle when its stopped and starting a new cycle.
* Can not save a particle, you have to set it up from scratch every time.
