It's a _must_have_ lifesaver.
But could you please allow users to scroll the cached items in your extension's window by just hovering the top bar and scrolling mouse wheel?
Just like Tab Wheel Scroll extension does for tabs on tabbar - I would like to see the same behavior in your extension with cached items. Thank you!
