Worked on improving user interface reliability in the godotengine/godot repository, focusing on refining UI interactions within the editor. Addressed a bug where the Escape key in the Find/Replace bar did not consistently cancel actions or hide the bar, ensuring that user input now results in immediate and predictable behavior. Enhanced the FileSystem tree navigation so that selecting files or directories works reliably, even under edge conditions. Utilized C++ and UI/UX design principles to streamline keyboard-driven workflows, reducing user confusion and support overhead. The work demonstrated attention to detail in user experience and contributed to a more stable development environment.
