Exposure time and aperture are shown in the status bar, but focal length is not, and it is equally crucial. Please, add it. Sensitivity (ISO speed) may also be interesting, and there's plenty or room. Besides, in the properties of the image, focal length is only shown in actual focal length of the camera (or lens), but it would be very interesting to see the 35mm equivalent as well. This can be done in parenthesis after the actual length or in the next line (can't make up my mind about either). If there's no time or interest in implementing these I can volunteer. Thank you so much in any case.

Thank you for your suggestions! I've added info on focal length and ISO to the status bar.
