Offer a "backlog" view
As a Product Owner I use the mind map to have an overall view of the feature of the product (mainly at the beginning of the project). In the case, each branch is considered as a user story.
However, the mind map is not able to show the priorization of the US in the backlog.
My wish is to offer a "backlog" view where each branch is a backlog item and the user can drag'n drop the item to prioritize them (and them group the item in sprints...)
