I did the same. I was relying on tree style tab heavily and kept 30-40 tabs opened all the time. Obviously without the extension this would be a pain. But then I realized that most tabs I have opened hang there for weeks and months without me even looking at them, occupying screen and mental space. Now I made a simple habbit: once I've read the tab and don't need it right now, I just close it. Should I need to return to it later, it's trivial to re-open it from history. One might think it's kind of a konmari approach, and when you're doing it you don't need extra management tools anymore.
