Hello everyone, I teach math and I am wanting to use the paintbrush but with the pencil showing on the screen as I'm writing. Or, if I could set different pixel widths for a thicker pencil, so what I'm writing shows up more boldly. Do I need to create my own paint brush? Or if anyone knows of another program that will allow me to do this, please let me know. Dankeschoen- Mathyu
