I have just had an email conversation with Kevin Wolkober about KuaiBoard and the way that it could be used in the classroom - saving time with feedback/ reporting etc. KuaiBoard is one of the third-party keyboards that was recently highlighted in the IOS 8 update. It allows you to store regularly used information, sentences and paragraphs which can then be inserted into messages and any application using an Apple keyboard. For more information, see http://www.kuaiboard.com
Kevin is interested in what we think. He is planning to introduce a way that the saved comments can be organised.
I'm excited to hear from you and other teachers on your experience using the app. I definitely think KuaiBoard is helpful for the classroom. In a future update, I plan to allow users to organize their clips into folders, and agree this is an important feature.
