Regarding my post (http://community.powerbi.com/t5/Service/How-to-handle-many-reports-in-a-workspace-on-Power-BI-Service/m-p/414342#M44616) I´d like to post an idea or better an request of improving the handling of many reports in a workspace on Power BI Service.
Make it possible to structe the overview of datasets/reports/dashboard in general and on the left side on Power BI Service like poeple want and also create an hierarchy possibility (like in OneNote) as well as an hide function.
Creation of more than one app for one workspace. With this option it is possible to share a choice of the workspace content for a topic related selection.
