The dashboard available as a tab in the FormulaShare app shows a summary of the rules set up, as well as total and recently applied sharing:
Clicking on each tile takes you to the underlying report which surfaces a bit more context around the data driving the component.
NOTE: We recommend not making edits to the reports which underpin this dashboard. Whilst this is possible, it could have unexpected consequences to the data displayed, and any changes will be overwritten with automatic package upgrades or installation.
The dashboard content is based partly on recent logs which have been captured, so if your org is configured to bypass creation or remove logs shortly after they've been set up (see the configuration overrides section) then some components may not reflect the accurate status of rules and sharing.
