0 gets LibreOffice notes for laptop screen.
1 gets LibreOffice presentation for external screen.
2 gets Hugin, pinned to 2 and 3, for laptop screen.
3 gets Hugin, pinned to 2 and 3, for external screen.
Then during the presentation switch between the workspaces.
Gonna have to experiment with this myself.
