One of the new features of 2017.1 is the added capability to work in perspective views.  This has been a nice feature as it allows for most tools to be used as well as temporary dimensions are displayed when things are selected.

A nice added bonus that I just noticed is the fact that add in utilities can now be accessed when in a camera view.  I have been frustrated not being able to access Enscape while in the view I want to be using.
