[REQ]: Add a "keep on top" window option

[3ll3d00d]

I find the graphs in the individual tabs a bit small so generally end up using the system graph screen maximised with the main window on top. The ability to stick the main window on top would make this much easier (I usually pin that to the bottom right and then scroll the system graph so the curves are still visibile).

This one may take a bit of investigation. I'm sure it can be done, I just don't know off the top of my head what has to be done.
