More options for wallpaper slideshow

Is there a way to add the following commands to the desktop (via a gadget or right click...)
- Next / Previous wallpaper button
- Delete(/Note) current wallpaper
- Move current wallpaper to a pre-set folder
- Keep the current wallpaper in it's folder but remove it from the wallpaper slideshow list

Additionally, is there a way to have the wallpaper to resize to a specific desktop zone, not the whole desktop?

Thank you in advance for your answer.

P.S.: .gif / .avi / .flv / .swf support would be great too (via vlc?) (with the option to mute the videos)

Next desktop is already a right click context menu command. I have no idea why you would need any of the others but I dare say they would be fairly easily to script and add to the context menu if you really want them.

Control Panel\Appearance and Personalization\Personalization\Desktop Background gives various options on how the picture is positioned (a wider variety than previous versions) so if you use pictures specifically sized to your requirements you can get the zoning effect.

The W7 desktop already supports .gif files. If you want video then I suggest you install Dreamscene (there's a tutorial around somewhere) but flash is not possible at present.

I've gotta ask though. Do you ever actually use the computer or just stare at the desktop background all day?
