The Sanity Studio is built from the ground up with customization in mind. You can extend and personalize the studio with your own styling, custom input components, custom previews and leverage our powerful plugin system.
We believe you should treat all your content as structured content, even your rich text and block content. In Sanity we call this structured block content Portable Text. It's designed to be efficient for real-time collaborative interfaces, and makes it possible to annotate rich text with additional data structures recursively.
Dashboard is a plugin to the Sanity Studio that you can populate with fully customizable widgets for different needs such as deployment, workflows tools, internal messaging, statistics and so on.
If you need detailed information about how the different Studio APIs and configurations you can go to the reference documentation.
