I used to use a Mac several years ago, and on that system, I used a program called GraphicConverter. GraphicConverter had a wonderful feature I wanted to ask you to consider implementing in Paint.NET -- "Rotate with Line". Here is how its user manual describes the feature:
It made straightening images a snap. For the moment, in order to achieve the same effect, I will either eyeball it or follow the advice offered here. But I would love the existence of this ability in Paint.NET. Regardless of whether or not you implement this feature, I thank you for the effort you've put into such a wonderful program.
