I just posted my first asset on Orbolt. It is the Kill By ID SOP that lets you select particles from the viewport and conveniently delete them by ID number instead of point number. You can also type in the ID numbers by hand as well.

It seems to be pretty fast and will work with particle fluids from DOPs as long as you enable particle IDs on the solver. Quickly get rid of pesky particles that don't behave.
