Boot with backlight on (as setting)

Yeah, seeing as how I made the animation that it boots with, I wanted this too. I forget the reason they couldn't do that. It's highly technical as I recall.

Better use of screen "real estate" e.g. show more data in VU Meter view

I disagree, I like the uncluttered look of the VU meter view. If I want more data, I'll use another view.

Wraparound menus

This one was an actual deliberate design decision by the team. It was discussed during the beta phase. If I recall correctly, the reason was that wrap around menus are sometimes a bit confusing to Joe Sixpack. I know us computer-expert types like them, but Joe Sixpack doesn't. For example, the Tivo doesn't have wrap around menus either, for the same reason.

Display battery charging when player off (as setting)

I thought it did. Hm. Maybe they removed that feature because of a technical problem.

Quicker method of selecting shuffle

I think that's probably the number one wish item for a lot of people.
