The new features in Lumigo aim to enhance collaboration among development teams for debugging and troubleshooting complex application issues. The tool offers message threading, which allows team members to start a new thread or add to an existing one on an issue, making it easier to investigate the root cause of problems. Additionally, threads can be marked as resolved, allowing the discussion to be closed and keeping the comments section tidy. Lumigo also includes screenshot annotation, enabling teams to attach annotated screenshots to their comments, providing valuable context for team members. These features contribute to a more successful and productive development team, better equipped to tackle challenging issues.
