Worked on the PCL-Community/PCL2-CE repository to enhance configuration clarity and user guidance within the UI. Focused on correcting a tooltip for the 'Execute command before launch' feature across both launch and version setup pages, ensuring users receive accurate instructions. Addressed a file-naming inconsistency by updating the configuration filename from option.txt to options.txt, aligning the UI with the actual file structure and reducing the risk of user misconfiguration. Utilized XAML for UI development, applying careful attention to detail and documentation. Delivered a targeted bug fix with minimal risk, emphasizing consistency and usability in the pre-launch configuration experience.
