in settings manager -> session and startup -> session
i find a list of applications and what to do when they accidentally terminate or crash (restart style).
with thunar it had the effect that if thunar crashes, it gets restarted immediately.
i want this behavior for pcmanfm, but there's no way of manually adding it to that list.
if i save the session and restart it still doesn't show up on the list.
so the question is:
how can i add applications to this list? i can remove them by pressing first quit and then save session.
i can add those native to xfce4, but how about others?
