I would some changes to how the text box functions. When writing text in the text box, I would like it to expand as you type, so the teacher can choose when to go to the next line. Also, when going to a new line, I would like the first line to stay where it is and the new line to expand below the first line. This should also apply when editing a text box.

Other possible changes....being able to choose the text size and color before typing. When clicking on the text button, it stays on that button (without having to double-click). These changes will help save teachers time from having to constantly resize/edit the text box after typing.
