The miniExtensions Form features a read-only mode for Airtable fields that you do not want users to edit. For linked record fields, there are more granular options available. You can set the field itself to not allow linking and unlinking, as well as creating new Airtable records. However, you can still allow users to expand (and edit, if desired) the already linked records. Essentially, any combination of view and edit access can be achieved, which opens up just about any use case!
