Vred renders per cycles.
when you launch a render, you usally set the N° of samples, or (if you have limited ammount of time) the time to spend in rendering.
sometimes it happens that you have to stop the render for whatever case.
in showcase, you had the option to leave the render going in view port and save it at viewport resolution when it reached an acceptable level of detail, so most of the times you did not actually waste time waiting.
now in Vred this is not possible in viewport mode.
the suggestion is either to add this option, or to add a button in the image render status window that saves the render at current sampling level, close to the abort button.
