Updated Family Types Dialog Box

The 'Family Types' Dialog box has been updated in Revit 2016 R2. Previously, tools displayed as text buttons. These are now icons to give us more real-estate in the dialog. As part of this change, you may notice now, you can click the modify icon for built-in family parameters. In 2015, the modify button was always grey, which sometimes caused confusion for those not in the know. 

In 2016 R2, when you click the modify, it displays a dialog box identifying it as a built-in parameter. You still cannot edit or delete this parameter, however it should make things clearer for those unsure as to why Revit won't let you modify the parameter. 

I like enhancements like this, I find in teaching, things like this help a great deal in explaining what Revit is actually doing and makes things clearer for the end user.
