The following improvements would make dashboards much more usable for our team.
1) the option to shrink the report size to the panel size (to minimize scrolling and using the "size" to draw attention to the important items).
2) being able to add text, both on top of panels AND as a panel/tile. Text will help us explain the purpose of a panel, highlight details, or explain what it's showing
3) being able to add shapes and pics
4) being able to filter the whole dashboard. For example, if I create a dashboard of "releasing this week" with both release and feature level panels, it would be great if I can filter the whole dashboard on a specific workspace or a status, without needing to adjust all of the panels.
