Add the lineal/ruler tool.
I cannot use OneNote as a functioning tool for my classes as a maths teacher without the ruler tool.
Please also add the "maths" functions from the desktop app to the iPad app.

OneNote is a very useful app. A ruler and a protractor will be very helpful for math and science courses.

Please add the ruler, it would make my life as a student using OneNote for all my schoolwork so much easier.
