Opera can show thumbnail of webpage in tab bar

Showing thumbnail of a webpage in tab bar is a unique feature of Opera.  In tab browsing, suppose I have opened many tags, I might find it difficult to navigate from one tab to another by just looking at the text on the tab bar.  With thumbnail in opened tabs,  I am sure I can get back to the right page.

In Chrome, there is something even more powerful called tab review.  It is a plug-in which can be installed easily.

Microsoft should learn from Google and Opera.
