similarly - I've been starting to look for something that lets me draw and write on a screen that can be transposed over video - would love to be able to do it live - like a wacom tablet with a screen.. So far the m-soft surface is leading in my limited research.. anyone know of software to use for such? Like network chuck does some writing during his youtube videos - but that may not be 'live' - and I'd ideally want to show notes / scribbles on a video shared screen like gmeet / zoom etc.. of course I'd love to be able to drag and drop boxes on a screen to show layout changes.. anyone know something that can do this?
