Have an easy way to expand the entire attribute hierarchy
Elements usually do not have tens or hundreds of attributes. A lot of the time, it would be nice to be able to expand the attribute hierarchy all at once rather than expand each parent attribute separately.
In PI System Explorer, Expand All has been a right click option in the Attribute and Attribute grids for some time. It is present when you either right click on the header row of the grid, or in an open space past the last row in the grid. In AF 2017 R2, we also added a Collapse All menu item for attributes.
