Hi @whazor! Thank you for providing the feedback and suggestion for the icon. Although we appreciate your suggestion for the keyboard icon, there doesn't seem to be significant difference. And we need data to prove that the icon that you've suggested works better than the current treatment. Do you have any user testing data to prove that?
