I like @hkeric.wci’s solution. This has to be added to each dashboard and/or customization. In the past, I wondered if there was a way to move ALL windows to the current or main screen. I found this solution on Stackoverflow.
In looking for that post, I discovered that one can also do a Windows+Shift+ArrowKey (left or right) to move the ACTIVE window from display to display as well. You can use Alt-Tab to rotate through the Windows to make the off screen window active.
Finally, this will be less of a problem with the browser since most windows today will be tabs and there will be fewer browser windows open to use the Windows+Shift+ArrowKey solution.
