Yes, radar interface is controlled with mouse like in original program. Off centering is possible to control with mouse or keyboard NumPad keys. In essence this is full screen "face-lifted" version of BC4.6 radar with added new features. I need to correct some things and add (reposition)PI lines mouse control and "beta" version will be ready for release. Please note that off centering mode don't have full sliding ability but user only can choose to off center "PPI" in one of possible directions (Front, left, right, back, front-left/right, back-left/right) for about 1.6 of current radar range. On maximum range off centering is not possible.
