A quick update on this post.
We used this in production this week and it worked great! I decided quickly though that this needed some form and style, not just function.
I also added the ability to be able to send a custom message to the screen!
The two buttons, “Send to Screens” and “Screens Back to Normal” in this panel are for my team, we use them to control MiniMEs on our Ross Carbonite switchers that send to our confidence monitors in the auditoriums.
I’ve updated the files on Github, if you want to go grab them!
