I would love to see the option to be able to add Lightning components into dashboards. In addition to adding in charts and tables from reports, there would be another button which lets you select from Lightning Components. This would include:
- Simple components. Rich text, images, news feed, home page components like quarterly performance.
- Custom components. This would be the equivalent of adding in Visualforce pages to a dashboard in classic mode, and will allow users to create any chart they wish on the dashboard. Dashboard filters could be an attribute within the LEX component.
- Record specific components. e.g. list views, record detail (would require a parameter on the component for record ID). Perhaps this could be a phase 2.
See example below of how I envisage this to look like:
