That s a good thing, so you can record to several sd cards, even if ml is not on them.
in camera-hdr bracketing is nice, but it would be cool to combine it with interval, so you can do hdr timelapse.
the overlays or a clean hdmi out would definetely be cool, but the most important thing would be zebras and peaking.
I can t wait to test it on my camera! great work!!!
