Developed a key feature for the spruceUI/spruceSource repository, focusing on enhancing idle monitoring configurability and cross-system compatibility. The work introduced a new command-line argument allowing users to specify a custom input event device path, replacing the previously hardcoded value and enabling broader deployment across diverse environments. This update was implemented in C, leveraging system programming and command-line interface development skills to ensure backward compatibility by defaulting to the original device path when no argument is provided. The change was clearly documented for future maintenance, prioritizing stability and minimizing deployment risk while addressing the need for flexible system integration.
