The ability to put a section underneath a section in the new Power BI App navigation pane. An example of what I mean is as follows: -> Marketing Reports ->2019 ->Report 1...
With the possibility to add dashboards and reports in the app, having only one layer of sections is a bit thin. Would be good to have the possibility of several layers of sections to distinguish where reports and/or dashboards can be grouped under but it would for example also be possible to create subsections by workstream or brand names, etc possibilities are very limited now with only a single layer of sections
