Allow loading / unloading an entire tab group

[hackel]

Firefox 4.0 introduces Tab Groups. I would love to be able to unload an entire tab group and load another. I am trying to use tab groups instead of multiple profiles to split up my work and personal browsing. When I start work, I would like to switch tab groups and unload all of the tabs in my personal group.

Another useful (optional!) feature could be automatically unloading all but the active tab group when you switch between tab groups.
