[feature request] find process by clicking on it's window

[Vladimir Rutsky]

Currently to find which process create window I start "xprop _NET_WM_PID" in command line and click on interesting window.

$ xprop _NET_WM_PID
<CLICK ON WINDOW WITH MOUSE>
_NET_WM_PID(CARDINAL) = 22409

It would be nice if user will be able to select process by selecting it's window from System Monitor GUI, e.g. by clicking special button "select process by window" and clicking on window.
