I am a mechanical engineering student and I need to write many large matrices in my notes and calculations daily. At least half of my class of 100 use ipads for notes and problem sets and I have heard the same idea from many people.

It would be incredibly useful if you added the large matrix bracket to the shapes that the shape tool recognizes. I mean "[" and "]" but with the ability to draw them as large as needed with straight lines.

This feature would be a game changer for many engineering, math, and science disciplines and I hope it can get patched into the next update.
