Examples of customized dashboards/admin pages and the queryable feature of Portable Text.

I don't see a traditional centralized gallery like you'd find with admin dashboard templates (Retool, AdminLTE, Grafana dashboards), but Sanity has several great places where you can find examples of Studio customizations to share with your team lead:

Best places to find Sanity Studio customization examples:

1. Sanity Templates - This is your best starting point! You'll find 40+ templates showing different Studio setups, from minimal clean starters to fully-featured examples with custom editing experiences. Each includes screenshots of the Studio interface. Check out templates like:

• Blog with Built-in Content Editing
• Turbo Start Sanity (battle-tested template from Roboto Studio)
• SanityPress (fully customizable with ready-to-use schema)

2. Sanity Plugins - With 1,300+ plugins (278 tools & plugins specifically), this is where you'll see tons of customization examples. Many plugins include screenshots showing custom dashboard widgets, input components, and Studio tools. You can filter by:

• Dashboard widgets
• Custom input components
• Asset sources
• Studio tools

3. Showcase Projects - Browse 570+ real-world projects built with Sanity. While these focus more on the front-end websites, many include details about their Studio customizations and editorial experiences.

4. Sanity Learn - Studio Excellence Course - Has visual examples of different customization approaches with real implementations, including a section specifically on "Pleasing Plugins."

5. GitHub - Search for "sanity studio" or browse the official examples to see open-source Studio customizations.

What makes Sanity different from traditional admin galleries:

Unlike admin dashboard templates (AdminLTE, Ant Design Pro, Tableau), Sanity Studio is a React application that's customized through code and plugins rather than themes. The customization capabilities are extensive and include:

• Custom dashboard widgets and layouts
• Custom input components for different field types
• Custom document actions and workflows
• Entire custom Studio tools (new sections in your Studio)
• Custom theming and branding
• Custom asset sources (like the Media Browser plugin)
• Custom diff components for version comparison

For your team lead: The "gallery" is more distributed across templates, plugins, and real projects rather than one centralized showcase like you'd find with UI kit galleries (Dribbble, Figma Community). This approach gives you much more flexibility than traditional admin templates, but means examples focus on functionality patterns and real-world implementations rather than just UI designs.

The templates page is organized into helpful categories:

• Clean templates - Minimal examples to get started with your favorite framework
• Full-fledged templates - Complete examples with live previews and embedded Studio
• E-commerce templates - Specialized for product and marketing content

I'd recommend starting with the full-featured templates section, particularly the official Sanity templates, which showcase modern, polished customizations you can deploy and explore immediately. Many include "Deploy to Vercel" buttons so you can spin up a live example in minutes!
