Oh hey! I built something similar a while ago, for somewhat similar reasons: "Pause Tabs" (<a href="https://chrome.google.com/webstore/detail/pause-tabs/gldljdhnehlgmkncfenmgfjblmmcjgce" rel="nofollow">https://chrome.google.com/webstore/detail/pause-tabs/gldljdh...</a>).<p>The use-case is <i>slightly</i> different, though--instead of being an en-masse "dump these things out of my sight" button, I basically wanted a single-page "bookmark" that works more like the real kind you use in books, where the two fundamental operations are:<p>> "Open, remove the bookmark, and restore reading to previous position, atomically"; and<p>> "Save position, create bookmark, and put away for later, atomically".<p>If you want, though, it can still give you the same effect of "hammer the button to 'put away' a window's worth of tabs."<p>On the other hand, the bookmarks Pause Tabs creates [despite just being regular bookmarks] preserve of your vertical-scroll position on the page, which is kind of nice for long documents. I wonder why that isn't a "built-in thing bookmarks are just expected to do", actually.
