Currently, modifying the start and end dates of an artifact requires navigating to each specific artifact's page to make edits. It is not possible to perform these changes directly within the Gantt widget view. This process can be cumbersome and inefficient, especially when a user needs to adjust the timeline for multiple artifacts, as it disrupts the workflow.

To create a more fluid and intuitive editing experience, users should have the ability to change the start and end dates of artifacts directly from the Gantt view. This would ideally involve being able to click and drag the edges of an artifact's bar on the timeline to adjust its start and end dates.
