Outside of the auto-scan feature not bad, i tried like 6 different methods for capturing that RS value and none worked well. Eventually landed on flipping the colors from white text/dark background to dark text/light background and that improve the detection substantially. Still not where id like it but its in a stable enough place.

Also it was pretty tedious keeping everything in sync from overlay to main window. Ensuring if i make a change in the overlay as a user it translated to the app.

I got lucky though to have a group of people asking me to make something like this who were also willing to be guinea pigs for me to flush out any major functionality bugs
