By nesting child tabs under their parent, the sidebar makes it quicker to scan, switch, and manage dozens of open tabs on Windows. The layout improves visibility and keeps related tabs connected so you can focus on research, development, or multitasking without losing context. Customization options let you control tab indentation, auto-collapse behavior, tab width and appearance, and you can drag and drop tabs to reorganize a session quickly.

I feel torn about Tree Style Tab. On one hand, it keeps my tabs neatly organized and that’s great. On the other hand, there are times it seems to slow down my browser. It's okay, but not amazing.
