Netlify has upgraded its form handling feature, allowing users to delete form submissions programmatically using the Netlift API or through a button on the form detail page in the app. This update provides more control over client data storage and gives users like @crgeary and @_brettsmith more flexibility in their dashboard management. The deletions are permanent, so users should exercise caution when deleting submissions. Users can now export form submissions to CSV and delete them with a single click or programmatically using the API. Additionally, Netlify will continue working on improving its form handling feature to better serve its users.
