Show HN: Octotree, the missing GitHub tree view

I started this as a weekend project and posted it on HN 5 years ago. 300,000 users later, I just released v4 today. Octotree [1] gives GitHub a sidebar that improves file navigation and code/pull request review. Works on Chrome, Firefox, Opera and Safari. Any comment or feedback is appreciated.
