Support adding plugins from different React/Framework instances

[literalpie]

We use tanstack query, forms, and dev tools in a large app that uses multiple instances of React (similar to microfrontends or "module federation"). It would be awesome if there way a way to add plugins from each React instance to the same dev tools.

Maybe something like window.tsd.addPlugin({name: 'TanStack Form', render: <FormDevtools />, defaultOpen: true}) which could be called in a useEffect (and another function to unregister the plugin when unmounted)
