Why I Spent a Week on a 10-Line Code Change

Recently, while working on implementing tab dragging in Warp, a terminal for developers built using Rust and a custom UI framework, the author encountered an issue where attempting to drag individual tabs instead dragged the entire window. After investigating and experimenting for over a week, the problem was resolved with a pull request that changed fewer than 10 lines of code. This mismatch between effort and output emphasized the importance of deep understanding in software engineering rather than just speedy coding. The solution was found by studying macOS documentation, examining open-source projects like Electron and Chromium, and ultimately discovering a commit message that detailed how macOS determines draggable window sections.
