The Design Collaboration interface has recently received some subtle changes.
The previous layout had the Timeline spanning the entire top part. While viewing the Team Model and with the Timeline expanded, the ViewCube moved down with it. You can see this in the below older screenshot sourced from the Autodesk website.

With the new changes, the Timeline no longer spans the entire top part. And when the Timeline is expanded, the ViewCube becomes hidden behind the Timeline panel. In fact, the Mini Map for the First Person mode is also hidden behind the Timeline. You can see in the below screenshot that it only takes a partial Timeline expand for the ViewCube and Mini Map to be covered up.

There may be technical reasons behind why this change was done. But the result is a degradation in navigation while the Timeline is expanded. The hope is that this can be addressed.
