Not sure overlay is the correct worsing in Xlobby, but here is what I would like. I want on a screen to ,on an event(button Press) , overlay on transparent background another "control" screen that may have additional buttons on it.
This is so that main screens remain clean and simple and ergonomic to use
I did not see how to have screen that was transparent. I guess then I would have a hidden button that called/exited the mini control screen?
