I agree. For example, I would love to be able to put a picture of a shuttle launch for a "Science" group, but use different pictures for my other groups. An added bonus to being able to set a background for each group would be that I could know instantly which group I am in (particularly when first opening a new tab) just by looking at the background. Groups I would like to have the same background for I could easily set with the same picture. I have another new tab addon that I used before finding FVD, which allowed me to use backgrounds for various groups, and that was the one feature I liked most about it.
This would be epic! Non offensive background for the work tab and more appropriate "F ur sense of decency" backgrounds for everything. Please code!
This would add a great "bell & whistle" to an already great extension.
