Not quite sure what you're asking. When you say "edit" an animated wallpaper - If you mean actually go into DreamMaker and make changes to an existing animated wallpaper and then save those changes, any user that loads the changed dream will then see those changes. If you mean just going into DeskScapes Configuration and selecting a different dream, or apply a DeskScapes Configuration filter to a dream, those settings will only apply to the currently logged in user.
Same type thing applies to WindowBlinds themes. If you actually edit and save the skin in SkinStudio, or change System Colors in Windowblinds Configuration, you are actually changing the skin and any user who then loads the skin will see those changes. If you just mean select a different skin within WindowBlinds Configuration, that selection only applies to the currently logged in user.
Is that what you're asking?
