Detail view panes take more memory and make longer the first loading of the main view, so by default only Task detail view pane is displayed among other panes.
To display detail view pane of a particular entity
By default detail view pane is pinned, so if you want to unpin the pane, click Pin in the upper-right corner of the pane.
To hide the pane, click Panes in the lower-right corner of the application window, and then click the required pane.
