Way back when public screens were new I wrote an app and uploaded it to ab20 amiga software ftp site, that would default to creating a public screen with the same specs as workbench was running at, and have a backdrop window with menu options to shanghai, pop a shell window on it, close down the screen, etc. I don't remember if I ever put in a screenmode requester option. It was called pscreen or something like that. I lost my old Amiga stuff over the years because of disinterest and moving. I presume the binary is out there some where on the net or on a cdrom of the old archive site. I could probably recreate the program source with updates if I found the binary to look at under an emulator to refresh my memory of what all it did. Now I'm looking at AROS so it could be useful again...
