a tiled preview would be very welcome,. could be on the bottom of the right panel perhaps.
agree w/ navot right click to move the camera would be nice,. (zoom on the mouse wheel would be cool too.)
perhaps you could do a combo left/right +up/down for the drag control? should work for both styles.
I figured out how to save images (just click on them),. but I agree the icon is confusing, use same one as save on main page.
Also, what formats are supported? I added .png to the file name and this works,. thanks again.
