User Story

As a content editor, I want to see an Activities component in the Edit Contentlet sidebar that displays recent activities related to the content, and I want to be able to add new activities, so I can easily track and manage content-related communications and actions.

Acceptance Criteria

• A new Activities component is created for the Edit Contentlet sidebar
• The component displays recent activities in a chronological list, showing:
  • User avatar
  • User name
  • Timestamp (e.g., "6 days ago")
  • Activity description or message
• The design follows the current UI/UX standards of dotCMS

Proposed Objective

• Technical User Experience

Proposed Priority

• Priority 2 - Important

Assumptions & Initiation Needs

• The current Edit Contentlet sidebar structure allows for the addition of new components
• The backend API provides necessary data about content activities

Quality Assurance Notes & Workarounds

• Ensure the new components don't negatively impact the performance of the Edit Contentlet
• Test the components' behavior with varying numbers of activities (e.g., none, few, many)
• Verify that long activity messages are properly truncated or wrapped
