The Importance of Perfect Freehand

I wanted to draw on top of my screen while I was streaming, like streaming. The problem with a stream of a mobile device is that you can't just wave the cursor at one part of the screen. And so I'd already made like a minimal drawing app for the state chart designer as an example. Wip up a electron app, it's gonna sit ontop of my screen. It's going to be transparent. And that'll, you know, just let me draw on the screen while I'm streaming. So in the same vein, perfect freehand right?
