Contributed to the zed-industries/zed repository by developing a Command Palette action that resets center-group pane sizes, enabling users to equalize pane layouts outside of Vim mode. Extended the existing recursive reset logic to function across nested split configurations while preserving the overall layout structure. The implementation included a dedicated unit test to validate correct behavior in complex, nested scenarios, ensuring reliability and maintainability. Release notes and documentation were updated to describe the new command and its usage. This work leveraged skills in Rust, GPUI, and UI architecture, demonstrating a focused approach to enhancing user interface flexibility and test coverage.
