I want to ensure that if I'm presenting using a specific screen, some windows (such as my private email or password manager) are never displayed on it. Is there a way to ensure that these windows are always displayed on my third screen, and that if it's disconnected (e.g., if I'm using only two screens in a different location), that these windows will be hidden or minimized?

Ok, fair enough. If you run out of enhancement ideas, maybe consider this one? I'm sure I'm not the only one who wants to avoid the wrong window appearing publicly when presenting
