I saw these at Tanto.

It was pretty spooky, they had covered a huge tree and several nearby smaller trees and bushes and even boulders. The big tree, all the leaves were dead. All wrapped in this silk, full of crawling larvae.

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.
