Pocket is a great solution for save all pages you will read back at later time (so the original name, "read it later"). But the retrieving of this sites is horrendous! This extension solve this by create a simple list of your saved sites (instead of a very busy page) and, when you click in one of them, opening site directly in a normal browser windows (not in a limited one). This behavior must be standard in Pocket, but I really don´t undestand why not.
