How I Use It
Users do need to prepare ahead of time and have screenshots to import (very easy ... but they do need to already be accessible) that start the demonstration of what we're going to explain. Another commenter mentioned they wished users could save portions of a presentation as we go and I agree. It is a bit frustrating to have to start all over when one small mistake is made. Just demonstrates the need to be prepared before you start!
This is a great way for students to show their learning of all sorts of topics. And for me to create content to share with students to use in the regular classroom or at home (ie "flipped" library classrooms)! Very helpful.
