Please consider adding the ability to do multi line equations. I have my students use the equation editor tool inside the textbox menu. It works OK, but they need to exit the tool in order to move to press enter. Then they need to grab the equation tool again when they start the next line. This is annoying and many students forget.
Using the equation editor in the main toolbar is even worse because they need to start a new box for each line of the problem. It is very challenging for students who have spatial issues to get things lined up and spaced properly.
