This is a great screen except that you can only see one line of the message you are typing - on PC using Chrome browser. It makes it extrememly difficult to write a long message back to a student.

Is there any way to expand the view of the message as it is being written?

This is also true for the small chat box as per screen shot.

[I understand this may also be a feature request but it also felt like a bit of a bug because the usability is limited.]
