I'm not sure what you mean by reviewing the note in your case, but perhaps the Note list preview plugin can help, as it can display the beginning of the note.
I know of 2 plugins that enable folding in notes (maybe there are others).
The first is CodeMirror6 Settings, which requires activating the beta editor from Joplin's general settings (and toggling code folding in the plugin settings). It works great for headings, paragraphs and list items, but does not save the state of folded sections. So if you switch to a different note and open the note back again, you would need to fold your sections one by one again.
The second is this one, which saves your folding state, and works in the standard markdown editor (not sure that it works in the beta editor at all). One way it works, is by adding a space and a period at the end of the heading you'd like to fold. There is also UI for folding, but I'm not sure it's still working (this plugin is quite old and not maintained).
