The Product Owner can view Theme reports that show how the progress of a specific theme is.
Statement from Kunagi Team
We aim to provide few "numbers" to represent progress. Additionally, the semantics of a theme "burndown" is not always clear. If a Theme represents some (concrete) epic, a burndown is possible. If the Theme, however, is more abstract (like "Usability"), a burndown does not make sense.
