During August 2025, Peter Schirmer enhanced the block/goose repository by delivering a redesigned main panel featuring a resizable sidecar, focusing on improved UI/UX and state management. He implemented auto-opening of the sidecar when tools return UI resources, refined the close behavior, and introduced smooth resize animations using setSize. These updates, built with React and TypeScript, addressed layout dynamics and reduced user friction, while also fixing auto-open and close bugs to increase reliability. Peter’s work established a scalable foundation for future UI maintenance, demonstrating depth in front end development and thoughtful application of state management principles to improve user experience.
