preview window

gordon, i think i was already talking about that once, but can not find the thread again, do u think it is possible to render output out to another smal window for preview, so if one uses dual display with controls on one display and r4 on second (like a beamer...) it is possible to preview on main screen? i mean if only r4 is used this is not absolutely needed but if u use r4 to mix with another vj tool this is verry usefull. i tryed to use "luminosity softcam" as a preview, but this is not verry productive since it causes a serious framerate drop of r4. i think it can not be that performance proplem if u write the output to a second small window...
