So good news.... when you are in the New Workfront Experience, you can select in the grouping areas of a report if you want it collapsed or not. For instance, I have several reports where the first grouping is opened but the second grouping is collapsed by default.
Also, in NWE, lists have a default of 2,000. So as long as you don't have more than that, everything is on one page. HOWEVER, please note that for dashboards, there is still the restriction options of 15, 25, 50, 75, 100, 200. You can't show all on a dashboard.
Hope that helps
