I am developing a little extensions called \"Tab Bundler\", which in short saves all the open tabs in a window into a bundle that can be opened with the click of a button. When
Look, many people tried this before. You are not alone in this quest! At the moment the answer in Google Code was: anybody asked for it when they where developing the History API. Then there's no elegant way to access tabs' history. Of course, you can hook chrome.tabs.onUpdated to record every page and make your own tab's history...
You could probably hook chrome.tab.onUpdate as well as some state or focus change hook to correlate.
I really want this, please make it!
