I unplug the iron, loop the cord loosely around it once, and let the plug end hang off the front of the table where I can see with a glance whether the iron is off.
In 30 years I've never unplugged everything else except my cell if it's charging, the charger, the TV, and the computer/laptop during a storm. Lived in at least 12 different places in that time with no problems. I may rethink it after reading this thread!
