Hi, I am new. I find Paint.net very useful. I would like to know (I didn't find it) how to freely rotate an image on the screen. I see only 90 degree left or right and 180 degree. Some time, for example I scan not perfectly righ a photo, or not perfectly levelled with my camera, so I would like to level it correctly with Paint.net but this is not possible, I suppose. There is any plugin that can do it? Thanks
