Center of sensor frame in Oculars plug-in

Hello. It will be very nice to see such a feature in Oculars plug-in as center of frame when using Sensor mode. It's showing lenght and width of frame according to sensor parameters and telescope focal length, but currently I have to click to some star close to the center to determine coordinates of that frame. It's useful for exact positioning during astrophoto of extended objects for proper cropping and framing, and also for calculating multiple neighbor frames for mosaic.

Thank you.
