Suggestion

Hi there! I'm a big fan of Graph in a society where everyone is so crazy about Geogebra. I use it not only to study, but I also try to make cute pseudo-artistic stuff, like in this video h t t p : / / w w w . y o u t u b e . c o m /watch?v=88acARRuqz4.
Of course the software is not art-oriented but it would be cool to have some features that made it easier, like a color picker that could follow a variable, for example.
