We’ve just covered that Opera 11 beta got Stack tabs feature, I am looking for something similar for Google Chrome and found Tab Stack Chrome extension. This extension doesn’t do what Tab Stack in Opera does, but Tab Stack for Chrome moves tabs so that they are always sorted in the most recently used (MRU) order, from left to right within each window.

With Tab Stack for Chrome extension installed, current tab will be moved to leftmost position in the current window, hence most recently used tabs are always to the left of tab list. If you cycle through tabs using Ctrl +Tab, then tabs will be accessed in the most recently used order.
