Worked on enhancing editor folding navigation within the JetBrains/intellij-community repository, focusing on improving the move-by-words command to respect folded fragments in the text editor. Utilized Kotlin and front end development skills to simplify the folding state API by removing the confirmation parameter from toggleFolds and aligning unfold behavior with toggleFolds, which streamlined the codebase and reduced maintenance complexity. This update addressed navigation friction in folded regions, making the editor experience more predictable for developers handling large codebases. The work contributed to improved maintainability and consistency in the folding subsystem, reflecting a thoughtful approach to editor and API design.
