New feature: Would you like to set a folder background image / wallpaper?

We're happy, but surprised, that so many users like the rather accidental feature of setting a thumbnail to a folder (see http://wua.la/moritz_/Images as an example). Two questions/ideas along these lines:

1. Would you also like to set a background image for your user/group? For each folder?
2. Would you like to be able to position your folders/files with the mouse (similar to your Win/Mac desktop)?
