Q&A: Why UI Zoom took three years

A long-requested UI zoom feature has been released for the Warp developer terminal after years of technical challenges. The implementation was difficult because the application is built on a custom Rust UI framework with hard-coded sizes, unlike web-based apps that get zoom for free. The solution involved repurposing the existing DPI scaling factor to trick the renderer into zooming the entire interface, not just the text. After this conceptual breakthrough, an engineer used Warp's own AI agent to write the necessary code in just 20 minutes, showcasing the use of AI for accelerating development.
