Is it possible to have the hierarchical structure of tabs like in tree style tabs (so I can see which tab spawned which tabs)?

It's not. But please make an issue on github[0] and if there's enough demand I will think about implementing this :) Contributions are also welcome, though the codebase currently needs a bit of a refactor.
