Beginning from version 0.4.0, TooManyTabs can now run in multiple windows. This is because instead of keeping separate copies of tab on different windows, we have decided to sychronize them in all windows. Therefore, if you add a tab in window A, the same tab would appear on window B. If you remove a tab from window B, the tab is also gone in window A. Technically speaking, by using the Firefox data storage (Places), we are able to track the transactions between different windows, and update the interface accordingly.
In this version, you can also add more rows, rename them or delete them using the options panel. Originally designed to hold some extra idle tabs to save your memory during a session, TooManyTabs has evolved to become a visualization of our web browsing habits. TooManyTabs is not just a a set of relocated bookmarks - in some way it is an overhaul of your Firefox browsing experience!
