I've been waiting for goodnotes to hit the Android platform for a long time, thank you very much for your willingness to develop goodnotes for android platform, add formula editing would extremely useful for students who studying mathematics or physcis at the university. Adding a formula editor, as well as handwriting recognition feature for mathematical formulas, such as OneNote would be beneficial. With Markdown syntax, code blocks can also be displayed, which would be very helpful for students studying computer science.
