manually selecting particles to delete/modify

[super gnu]

I dont think you can select individual particles unless its baked out and no longer a sim.

there is a delete operator you can use, but that will delete random particles unless you make a certain test for them. to add particles to a group or remove all particles I think you have to select the tyflow object

iirc you can select particles in pflow in the viewport, and delete/assign ids for use in the sim.. i would assume there would be equivalent functionality in tyflow...

extremely useful for art-directing purposes.
