The whole problem of a tab UI for power users with hundreds or even thousands of open tabs (like me) is mindblowingly daunting. I don&#x27;t know that tabs on the side is the solution. For a long time I&#x27;d been using Tab Groups but I&#x27;ve been frustrated with its limitations.<p>Ideally, I think I&#x27;d like something similar to the spatial system of the Classic Mac OS Finder, which I coincidentally expounded upon recently in another thread[0]. Tab Groups goes part of the way there with its spatial organizational system but it lacks the hierarchy and persistence of those Classic folders and desktop.<p>[0] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11664984" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11664984</a>
