Small, simple package; outstanding power.

Its not easy to pull off a perfect balance between utility and simplicity, but this app (both iOS and OS X) nails it! So much power and capability in such a light and simple interface deserves nothing but praise. Many other apps of this kind have a lot less capability in a much more cluttered GUI.

Ive never seen a better, simpler setup for math at such a reasonable price.

Suggestions:

- Night mode! That white background can get really bright when youre working on a project at 1:00 A.M.
- Better formatting for note-taking. This is one HUGE advantage of, say Mathematica. Being able to present problems with annotation would be a major plus in my book, and the comment capability isnt quite enough.
