Train of Tabs

A scenario: 1. You open a whole bunch of tabs 2. You switch to something else (another application or you go make some tea) 3. You come back to the browser and wonder: what was I intending to do? Where did this tab come from? Which tabs are the links I was gonna follow up from here? This is a simple extension that helps with these questions. It keeps track of which tabs you opened from which other tabs and, if called up, at any given tab it will show you that information.
