Really the only time you need to let the turbo idle to cool down is after you've ran it really hard. That's when it's at its hottest and can most easily coke oil onto the bearings. If you just took a lazy drive to the grocery store and back, it's not completely necessary to let the car idle to cool the turbo down. It's not a bad thing to do, I'm just saying it's not necessary.
I also park my car in gear all the time, so even if I had a turbo timer, I'd still be sitting in my car so I could put it in gear when it turned off.
