Add a way to edit and view particles visually, as editing only the properties in property editor does not help visualize how the particle effect is going to look. Support toggling the effects on/off, pausing, resuming, and scrubbing the time back and forth. Only the selected particle system is animated to allow concentrating on that particular system without being confused by other possible particle systems.
