Idle time runs whenever there is nothing else to do.  As such, it cannot be disabled but if you really want to do nothing, choose the Sleep option for all time periods and you will simply see a countdown to the next routine starting.


A better option is Close Game which will close the game completely and start it back up again when your next routine is ready to run.


Hover over each Action box to see which time period it applies to.



Idle Time does NOT interrupt your routines. It fills in the gaps between routines.  


If the Idle Time routine starts, it is only because Ragebot has nothing else to do.
