Please add any feature requests here!

There's a lot of features I would like to add to this tool. While I will be working on other projects, I will come back to this tool every now and then to add new tools and features; I'd appreciate if you let me know which features you'd be most interested in.

Some of the ideas for tools I have in mind are one for visualizing complex functions, one for visualizing 3D surfaces of the form f(x,y,z) = 0, and one for drawing fractals. Some of the ideas for additional features I have is a way to save gifs.
