-Wall Paper randomizer
-Ability to delete seldom used NXE options
-Web Browser (not that I need it, but it'd be nice.)

Web browser is needed.

The ability to switch to the old blade interface.

I like the old blades much much much much more!

Able to remove, those pesky, spotlight, events, channels, like welcome channels.

a room for your avatar to be in, and on the walls it shows your latest achievements, a tv showing the game u are playing or currently playing, the ability to get items to show off in your room, like plush viva pinata animals or a marcus figurine to put on a shelf.

some pretty cool stuff on that list. It would be cool if like Jaggedsac said you get rewards for certain amount of gamerscore. Like if you hit 20,000 you get a free Arcade game or something. The gamerscore system is incredible and I'm so glad they made it but they need to introduce something new to keep people wanting to get achievements.
