I have a permanent thermometer in my brew pot. When starting the boil I know to stay close at 205F or so to prevent boilovers. Until then I am free to do other chores without too much to worry about.
At flame out I start water through my immersion chiller and I watch for the the wort to get below 140F since at that point I can put the lid on the kettle without DMS fears and reduce the chance of other airborne contaminates getting in the kettle. At that point I'm free to do other things with the convenience of a quick glance at the thermometer to monitor chilling progress.
YMMV - I would miss it now if I didn't have one.
