Hi, let me ask you for things I don't understand. You did a patch for
hiding particle system from 3d render viewport.
I always thought that there are buttons for that in Render and Display
subpanels in particles setup. Namely Render -> None, and Display -> None.
They act exactly like you've described, so please clarify this for me ;)

Is this independent display switch for all particle systems on the scene?

best regards
