In AX2012 we used to have a super cool way how the different hierarchies in the system were visualized. It was a dynamic visualization, with curved lines between the nodes of the hierarchy and a super cool way of showing a changing view when for instance you clicked to go a level lower.
Nowadays, the visualisation is very poor, actually pretty useless. The view does not really show a hierarchy, but just several disconnected blocks, and it is not dynamic anymore.
Please find a way to return to the old way of visualizing hierachies.
