Several architectural improvements have been added to Essential BI Client to enhance performance, filtering, report manipulation, scrolling, and action modes. They include an enhanced tree view and a report list that allows users to save multiple reports and switch between them. A filtering icon in the axis element builder can be used to indicate which members are filtered. Also, virtual scrolling and JSON mode support have been added to the grid to further improve the control's performance.
