I'm really pleased to see that this actually outputs plain text results in _plain text_. For example, if I enter `Integrate[Sin[x], x]`, the result is `-Cos[x]` _in text_.
Real, honest to god, copy and pasteable text!
This is at odds with Wolfram Alpha and integrals.com (from its inception to its current integration with Wolfram Alpha) which returns you... a gif. Of Mathematica-rendered text. Ugh.
