It would be helpful if the IDLE trigger could include a trigger for "seconds" instead of just "minutes". As a workaround, I have to use the Periodic trigger and then calculate if the requisite number of seconds has passed. This causes my Debugger window to get cluttered with macros I don't want to see.
I wouldn't be upset if the minimum number of seconds was set to something modest like 5. But 60 seconds is just too large for me.
