Heres 2 to start off....
Shutdown Pop Up Window (Idea):
Having the 'Shutdown Timer Selection' window popup ontop of any other window in RR.
That way, it doesnt matter where you are (in what screen), if you turn off ACC the window appears (fade-in, popup, dissolve, fold-out, etc) and you can select the option you want and then leave the car. Or press the 'Dismiss' button, if you want to leave it as is.
Shutdown Timer (idea):Along with the other timer options (perhaps which can be user defined), can we have an option that is 'Shutdown After CD Rip Completes'.
I have no idea how to check for this, but it would be neat. I often start a RIP and leave the car to go inside.
