A great, simple, and lightweight extension to discard multiple tabs. It has great features and easy to follow options. However, I'm not a fan of the latest update that changes the gray dot and grayed out tab when discarding a tab to the blue "zzz" icon and not graying out the tab. I prefer the former because it's easier to tell which tabs have been discarded. The blue "zzz" icon is also a bit distracting.
