Please not. (We really need a new Style Guide.)
Amiga windows close always immediately when you click on the close gadget. Requesters asking if you want to quit are appropriate when a program still has not yet saved documents open. From there some programmers seem to have the idea to ask always in return of the close gadget.
I find this behaviour annoying. (And, because you will be used to click on yes without much thinking, it will devalue the requester where is really danger of data loss.)

UBoot is in flash memory and needs no power to survive. The battery is a CR2032. I don't think that this type will be disappear - it is used in many devices. And I think you can save your NVRAM settings with prefs/UBoot.
