Open Source Contribution: Octotree
A coworker introduced me to the chrome plugin, Octotree. It provides a tree view for any repository you're viewing on Github to quickly navigate between files. A few people had submitted issues requesting a filtered tree view for pull requests that only shows files that are changed. I wanted that feature as well since our company had moved to Github for source control and pull requests.
It was fun diving in to Github's API and learning about a different Javascript architecture than I was used to.
