You can currently make an entire workspace a template which is great.
But it would be awesome to be able to templatize individual panels or visualizations.
For example: templatize the fallout visualization for checkout. This way users throughout the organization can easily drag it over for their custom workspace.
Currently, having to duplicate a templated workspace then remove all the components that aren't needed is cumbersome. This would also be a powerful way to standardize reporting throughout an org.
