During August 2025, 4o4@rawbytes.net enhanced the gitbutlerapp/gitbutler repository by expanding file icon support within the UI component library. Focusing on front end development with TypeScript, they introduced mappings for new file extensions such as .cts, .mts, and .graphqls, enabling the interface to display appropriate icons for these file types. This update improved file-type visibility and streamlined navigation for developers working across the codebase. The implementation maintained alignment with existing icon rendering flows, ensuring consistency and traceability. By establishing a scalable approach to icon mapping, 4o4 laid the groundwork for easily supporting additional extensions in future UI updates.
