On the document tab, the 3 view available are 'standard','thumbnail' and 'list'.
The Workfront functionality is that the 'standard' view is the default for the documents tab.
This idea is to have the 'view' remain to what the user had the last time the user was on the Documents tab.
On the Task & Issues Tab on a Project, the view chosen by user remains the same as a user navigates to other Projects.
Also note, the List view provides the same type of view that is displayed on all other screens throughout Workfront and that is why we need it to stick on that view. Documents doesn't display "Filter", "View" and "Grouping" dropdowns by default but all other screens do.
