Requesting a "custom fields" setting tab to place in "Pages" backend.

This tab would allow administrator to add different type of inputs and media images. The fields and media images will be user friendly enough for administrator to arrange the order as they want.

This is already added in the static pages plugins, but it should be add to CMS tab too.

Yes it is integrated but currently I only find image and input text field only. It would be ideal to have other input types like date and select fields for example.

This is an example I have in mind. https://wordpress.org/plugins/advanced-custom-fields/screenshots/

Is this what you are looking for? https://octobercms.com/blog/post/builder-idea If so, it is currently being developed

Yes, that's what I have been looking for. I am still waiting for its release.
