Comment 5 for bug 1245355

The popup could theoretically be hidden when there's only 1 display, but I'm not sure how this would "make things the user could want to do harder". The popup is really tiny and it should be easy to move things to a different area of the screen in case the popup actually hides something useful (I can't imagine what though).

An additional option just for that seems really superfluous to me, I'd rather not clutter the UI with checkboxes for stuff like that. I think the RAM usage of this tiny popup is rather negligible (especially as it's not persistent but only shown as long as the dialog is open).
