Sometimes when looking at some project's source code on GitHub, it is hard to navigate and find files without cloning the whole repository.
Buu Nguyen has built a great tool to solve this problem: Octotree. We use it when we look and work with open-source libraries.
Octotree is a browser extension that scans the project on GitHub and shows its file structure in tree format that is easy to navigate. This way you can explore any project contents and jump between files instantly. Working with third-party libraries is now more efficient.
