To be honest, no I'm not sure... something I regretted already... Sorry!

Also talking about visible names I'm not sure about "Idle" as well...
Every time I read it get confused... I believe it is because PSR active
needs Idle usage...

What do you think about changing to Idle to Enable-Exit and Active to
Enable-Active?
