You know what's sad? I logged in only to comment in that topic. The sad thing is a fact, that this feature is present on different, most popular browsers on the market. This feature can save a lot of work, time, and in consequence - money, for us, for people. And instead of thinking about a way of implementing this to, in my opinion, excellent browser, you're giving us pointless tips, because in my case, I've never even seen that button 'Reopen Last Closed Window' in History menu. If you can do something about restoring closed opera windows - I'd be really glad.
