Will be removed in next version of plugin (not the version from today)
Waw. Thank you for your feedback.
Thank you for suggestion. I will add it to list of issues.
What do you suggest as notification to inform user about problems with API key?
For some users of plugin is valid API key critical (In the past another user reported, that he needs in case of any problem with API key big red notification on every admin page.)
If you need introduction of all features, we can provide one on one demo for you.
