Whyline

In an unfamiliar codebase you often hit a line and think, why on earth is it written this way. git blame only tells you who touched it last, never why. Whyline lets you select a line and stitches together the pull request that introduced it, the review comments, the issue discussion, and related commits into one timeline that reads like a story of what someone was trying to fix. Instead of deleting a line on a hunch and causing an outage, you grasp its context in five seconds before you touch it.
