>1. Always ensure your windows are within the bounds of the same screen that you launch

Are you referring to :
1- additional main windows,
2- or to sub-windows of the same main window,
3- or both ?

If 1 or 3, it beats the idea of having a multi-screen app.

If 2, I guess it should be the job of Qt to enforce that rule, in
order to avoid duplication of efforts.

May I point out that Qt distinguish two different ways of dealing with
multiple screens :
- multiple screens logically fused into a single virtual desktop ;
- separate screens, each with it's own coordinate system.

In the former case, apps basically see only one screen.

In the latter case, since the desktop is not extended to those
additional screens, I guess it is fair that no user interaction would
be expected, and hence fixed main windows with no QMenus, nor dialog
boxes or tooltips.

If a single virtual screen, I see no reason other than artificial
internal reasons to prevent the user from moving / creating windows
all over the virtual screen, including having windows that span
several screens.
