As a primary teacher, I have to be as prepared as possible with as little wait time as I can manage for my youngest learners. I would like to be able to have 2 different documents open in different tabs. If I attempt to do this, it will inadvertently update one to look just like the other tab. I do not want that. I want to be able to switch from reading to a math activity. Not having to end one lesson to look for, then open another one.
