Instead of presenting it all as one long mash up dashboard, it would be nice to update the presentation/layout for users/groups that login, with titles and page breaks or some separation.
3x3 and 2x2 should be customizable to add whatever rows/columns desired. [5x7, 3x5, etc.]
When adding a reportlet , do not cut off data in the reportlet viewport due to size. Either display it all or show a popup or something stating you can only use X columns.
Thanks for requesting this! We're also struggling with such limitations when building dashboards and exporting reports to share with internal/external clients. Judging by the fact that this ticket was open almost 10 months ago makes me wonder if it'll ever be tackled.
