Also, the same thing for writing files. I have a program that reads data from 3 matrices and displays an output based on that, and I think it'd be useful to save a preset by writing the matrices to a text file. I know you can do this by programming your own text prompt and using that to type in the location of the file you want to load/save, but I'm wondering if there are any GUI file browsers that will still function once I've exported the sketch as a standalone application.
