Thank you for your feedback. I am very sorry to hear you were not entirely satisfied with the quality of the add-on.
I have released an update to remove the promotional messages.
Please note that each message is only shown once, and there are only two message, therefore only 2 searches will have a message embedded at the top. It should not affect searching too much.
The reason the message were displayed:
I was planning to add functionality to inform users of changes (for example if Google change their code and the add-on temporarily stopped working). I would do this through these messages. To test if they were working correctly I added 2 self-promotional messages: - The first asking users to rate & share the add-on - The second to promote another one of my add-ons
I could use that to check if the messages were working correctly because I could analyze the download sources of my other add-on (to test the second message), and quote share text in Google (to find who shared the add-on using the first message)
The messages have now been disabled. In the future I will add an option to enable or disable messages and informative updates.
Thank you for your idea of creating an icon of the top of the page, when I re-enable the messages in a future update (with an option to disable them), that is what I will do.
