Just learned a couple new things myself, not sure if they're common knowledge.
The sunroof (if you have one) can be opened completely. If you do the 1-touch open, or hold the switch down, it stops with about 1" left covering the opening (at least on my car), hold the switch down again and it will open a bit further.
Also found out that the window and sunroof switches work even after turning the car off and pulling the key out. From what I can tell, they work until the driver's door is opened. So if you forgot to roll your windows up or close the sunroof, instead of putting your key back in and turning the car on, you can either use the door lock feature to close them, or simply hit the switches.
Oh, working on the regulator write-up, but a friend is in town this weekend for a wedding and we're going to do some drinking, so don't expect to see it until early next week.
