Our existing Timeline View calculates the vertical position of events automatically to keep them in order and avoid collisions and overlaps between events. This supports general workflows involving filtering and time scale changes, but it does not provide fine-grained control for creating presentational timelines.

This feature would introduce a separate mode that would give users more direct control over the vertical placement of events in a free-form timeline at a fixed time scale.

We may also look to introduce further display features such as being able to edit event appearance and provide additional annotation and decoration to a timeline beyond the core event data.
