Why This Is a Problem

• Data Accessibility Issue: Users lose access to their contact list and events, and upcoming events which is crucial for managing family connections and brings inconvenience.
• Frustration for Users: Users are unable to recover their contact list using available commands, leading to a poor user experience.
• Workflow Disruption: This issue forces users to restart the application or other means/commands to regain access to their contacts and events, disrupting their workflow.

Suggestions for Improvement

1. Modify the find command to ensure the interface restores the previous list view when no matches are found.
2. Display a user-friendly message when no matches are found, such as:
   "No contacts found matching 'Jack'. The full contact list is still available."
