Preset Feature Feedback
The current interaction for seeing chart descriptions in dashboards is to select "Toggle chart description" option in the chart menu. A permanent description then appears in the chart widget.
Consider changing this pattern to reveal the chart description on hover in a tooltip for consistency with the chart CRUD views.
This feature would bring a lot of value. I can't tell you how many times an end business user comes to me looking for more details about the exact nuances of a chart. Being able to include a little information icon that can show the chart description when a user hovers over it would be incredibly useful.
