RFE: Restore workspace windows

[pjoc]

I use and like the "Restore window's position" setting. However restoration doesn't take into account the workspace (virtual desktop) each window was on when saving, so every time I log in I have to spend time moving windows around as they all restore onto the same desktop, and which one it is appears to be either random or the one I happened to be on before logging out.

I'm using Linux (Fedora) with KDE/Plasma. I don't know if the same happens on other DE's or other OS's. This would be a much appreciated improvement to my workflow.
