How about adding a way to create public screens in Workbench in some way?
I have been using
http://aminet.net/package/util/cli/newps to create new screen, to put some programs on like, EaglePlayer that can be moved between screens.
When starting to use AmigaOS again after so many years, applications creating their own screens, sliding screens up and down, using Amiga-M to switch screen is really the signature feature of Amiga, in my opinion.
I find it strange that AmigaOS never had this capability from the Workbench GUI in some way.
