• Timeline UI would typically be shown:
  • In cases where a primary model (Contact/Party) has many relationships to time stamped data in secondary, related models (Notes, Calls, etc.)
  • Timeline UI would appear when user "pins" app to a particular Contact/Party as an alternative to simply filtering an item grid view to a single row

Tasks

• Design Timeline component
• Implement Timeline component
• Add any required global state or metadata related to Timeline view
• Implement Timeline data fetching/caching logic
• Add reactive logic to items grid toolbar, items grid views menu, other existing UI elts that need to know/represent that a timeline is displayed
• Testing, refactoring, documentation
• Integrate template changes into a solution
