What does the suggested spin component provide over than the circular progress component, linear progress component, or skeleton loader component?

@mohammad19974 Could you share instances or scenarios in which you see the Spin component being more beneficial than existing loading components such as Circular Progress or Linear Progress?

I agree with @zprobinson and @yasminebeji. Please share more details about the use cases and examples (maybe screenshots, recording or mockup).

<Spin spinning={true} indicator={< Circular/>}> <div>Hello</div> <div>Content here</div> </Spin>

the spin :loading (with backdrop or not ) wrapper on content

This seems like something that the components exposed in mui joy already can be used to create, with not too much difficulty.

Where is the threshold between what the library exports and what consumers of the library can create as a reusable app component?

Thanks for the clarity. It looks like an Overlay with loading component.

It's hard to justify but most of the time we prioritize component based on issues upvotes.
