This extension provides the ability to work with tabs as “trees”.
New tabs opened from the current tab are automatically
organized as “children” of the current tab.
Such “branches” are easily folded (collapsed) by
clicking on the arrow shown in the “parent” tab,
so you no longer need to suffer from too many visible tabs.
If you want, you can restructure the tree via drag and drop.
Click on Power icon on right top corner of panel to
backup tree structure and shut down browser 📴.
