Tab Stacker is described as 'Moves tabs so they are always sorted in most recently used (MRU) order. Pinned tabs will stay in place'. There are four alternatives to Tab Stacker for a variety of platforms, including Google Chrome, Linux, Windows, Mac and Online / Web-based. The best alternative is MyPages Chrome Extension, which is free. Other great apps like Tab Stacker are TooManyTabs (Free), Tab Wrangler (Free, Open Source) and Tiny Suspender (Free).
Do you have many tabs open - sometimes TOO many? Are you unsatisfied with the standard Chrome Task Manager? Would you like to easily search, sort, filter the list of your currently open pages? Or do you use Chrome often on multiple computers?
Ever tried having 20 tabs or more open in Chrome? You can’t even see the favicon of the tabs, not to mention the tab titles! If that happens to you, TooManyTabs is a must-have extension that manages your tabs, reduces your tab overflow, and saves your sanity!
