John Stegeman developed the Working Copy Change Count feature for the Jujutsu segment in the oh-my-posh repository, enabling users to see the number of local changes relative to the nearest bookmark directly in their prompt. He updated the Jujutsu logic in Go to compute this count accurately, introduced a configurable icon, and added an optional fetch capability. John also revised the data schema and enhanced the Markdown documentation to support user configuration and clarity. His work focused on improving prompt reliability and developer productivity, delivering a well-contained feature that increased workspace observability without introducing unnecessary complexity or surface area.
