Summary:

Add a timeline view that would reflect the current phase of the given issue type. Let's assume that each issue type (Epic and above) is split into certain phases within an organization. As of now, you can modify the bar on the timeline to reflect a specific color based on the value within a custom field, yet it'll alter the entire bar, and there's no possibility of seeing the big picture - the bar split into multiple sections for each phase.

Some complex pieces of work, like Features, Initiatives, or Sagas, require a significant amount of time to complete (1+ years), and it'd be beneficial to see the exact phase at which the given issue is currently at.

Let's assume a scenario, where 4 phases are planned for a Saga. The timeline should reflect a separate color for each phase, including the timeframe of the given phase.
