I can't describe in short how Tree Style Tab improves tab management.<p>* You can logically organize tabs, very valuable when you researching something, or when you work on multiple related web pages. Say, issue tracker, a PR or two github for this issue, a couple of doc pages related to the code, etc. The beauty of it is that the tabs mostly self-organize based on the opening order.<p>* You can expand and contract whole subtrees to keep current things in focus, and other things, readily available.<p>* You can have 30 or 50 tabs and still actually read the captions of the tabs!<p>* You can bookmark the whole subtree, or move it to a separate window, or close all of its tabs, or refresh all of its tabs, etc.
