I haven't bought this program yet, so I don't know if something like this is in or not, but will there ever be a way to toggle off blink tracking? My main concern with buying it is I tend to blink a lot and commonly have trouble syncing both of my eyes to blink at the same time. This is already pretty awkward and would make the tracking result even more awkward. It would be nice if the program had a toggled option that would still track the eyes for positioning of the rest of the face, but would blink in a varied changeable interval. If eye expression was needed for something the auto blink would just be toggled off and then back on.
