I would love to have something I had in Cobalt- the ability to step the view in defined increments along an axis, so I could rotate the view easily and precisely only along an X, Y, or Z axis. In Cobalt the View Cube equivalent had a "step" mode, similar to the Fusion orthographic views but with much finer gradations. Also the ability to save and name specific views.
This is very useful when you are trying to evaluate complex shapes with few flat planes.
