Sansa Clip+: Power on protection and low battery bookmarking?

[gomezz]

Would it be possible to change the power on to use a press and hold (as needed for power off) rather than a simple press?

And would it be possible for an imminent low power switch off to allow for a bookmark to be automatically taken before it closes down as it does when manually powered off?

For the first question, probably not.  Maybe it could be faked by modifying the bootloader to shutdown quickly if the button isn't held, although I don't know how the timing would work out.

I think bookmarks should work automatically even on power off for low battery, but its possible they don't.

I also dislike this behavior and use rockbox with attached patch.
