Feature

You can add a right click Menu. For example: if you right click on a tab, you can duplicate the tab or open the tab in a blob URL/about blank. You can also maybe (if this ever becomes a feature): put the tab in full screen, use the inspector/console, or add a page to another page called "shortcuts". (just like bookmarks.) 

its ok if you don't wanna add this. It's just an idea. :D
