I really appreciate Nomacs jpeg rotation because it doesn't decrease image quality. However, for jpeg images whose dimension are multiple of 8 a lossless rotation according to jpegtran rules should be perfect.
I don't want another menu entry or button or shortcut but Nomacs should be smart and it should recognize those images whose dimension are multiple of 8.

we rotate images using a flag in the metadata - hence, rotation is lossless even if the image size is not a multiple of 8
