graphDS WIP progress update

I just wanted to post an update on the progress I've been making recently on graphDS. I am very proud and excited to announce that I am developing a CAS that will be able to simplify polynomials, find derivatives symbolically, and possibly perform limited amounts of indefinite integration. Currently, the CAS is only capable of adding, subtracting, and multiplying, so it may be 1-2 weeks before the next release. v0.8 will also include the capabilities to draw slope fields and Euler's Method, as well as some more built-in functions.

Check out the screen of my CAS:
