Great extension.

However, I think its biggest weakness is that if you accidentally click a suspended tab, it automatically begins to load. This usually happens when you close a tab and the browser automatically jumps to the tab to its right that may be suspended. That is a big turn off. Every suspended tab should have a "this page is suspended" window. And also the extension should have the option to let the user manually reload a suspended tab with a click, in contrast to auto reload.
