What can I customise in Laravel Nova?

Everything that matters. Custom resources for any Eloquent model. Custom fields (we have built fields for signature capture, location pickers, rich JSON editors, and complex relationship pickers). Custom tools that live as full pages in the Nova sidebar. Custom cards on dashboards. Custom metrics (value, trend, partition). Custom actions for bulk operations. Custom filters for advanced search. Custom lenses for alternative table views. Theming, navigation, branding, multi-tenant scoping, and role based access through Nova policies. The Nova API exposes nearly every part of the panel for customisation.
