tree in 1.6.0-nathalie is as simple as possible. U could only assign teams to node. At the Backend U could also assign matches to node, but it is NOT shown on frontend. All additional feature will be available as a extension (maybe free, maybe paid). U could see possibilities at treerank extension demo.
