There are several addons that organize the tabs in the sidebar with a vertical, tree-style layout, with nested tabs that can be collapsed, just like a classic folder structure. This is what GreyBeard was referring to earlier in the thread. Tree Style Tab has been around since 2007; Sidebery is much newer, and IMO looks and performs better.
You are correct, TreestyleTabs was my jam for years, but I have moved over to Sidebery because it performs better and has better support for containers, as well as being considerably more customizable.
What are these tab trees? Is that an addon?
