Hey everyone - long it lurker and first time posting.

So I've been playing around a Toaster/Flyer setup for the past two years. It's all up and running smoothly in an A4000 with the media drives converted SD cards (capturing and playing in HQ5). While playing around and learning shortcuts, I accidentally found the Flyer TBC Control screen. Does anyone have any idea what this is? Is it active/usable? I know there are inputs on the Flyer Card, but I haven't played around to see if they work. Does anyone have an insight into this?
Additionally, are there any more hidden screens like this? I would love to know more.
Thanks!!
Greg
