Is Better Trello safe?

Clean risk

Better Trello stores a Trello Butler automation token from Butler requests in local extension storage.

When Butler for Trello requests include an X-Butler-Trello-Token header, Better Trello reads that header and saves the value as butlerToken in the browser's local extension storage. Its popup then displays the stored token in a Get Automation Token field and offers a Copy to clipboard button.
