I just realized the Settings-Screen in the latest Mac version (AgileBits Store version) looks odd in German. I think the text spacing went wrong.
Additionally when the App is locked under "Accounts" the button for "Subscription" active is still clickable and then there's an error that empty login credentials are not allowed. I think it would be better if you couldn't click on anything there in the locked state.
Also I would prefer it if the first characters of the Secret Key would be hidden in the locked stage, but this is not a bug.
