I'd be interested to see the support of lossless jpegs transformations extended with the functionality that is offered by the standalone utility JPEGCrops.
JPEGCrops offers various standard width/height ratios as well as you can define your own.
It displays "golden section" or "rule of thirds" reference lines, which are a great help to position your crop region right.
And it does the automatic rotate, if you will.
It's a lovely old tool, which I use at a regular basis to trim my 4:3 CCD images to 15:10 paper size, and it would be nice to have this added to XnView, if possible.
Regards,
Stephan
