It bothers me because ps shows swapper task on offline cpu and other active
tasks are in the same style. What I want is to show it is different. I wish
to distinguish the swapper task on offline cpu directly without having to
check which cpu is offline firstly.

I would like omitting ">" of idle task on offline cpu and adding "[OFFLINE]"
at the end of the line when "offline" set to "hide". And maybe you would like
adding "[OFFLINE]" at the end of those sleeping tasks of offline cpu as well.
