But even with fisheye pictures optimization settings are kept if I start with the "New Group" button. They are not kept only in two cases: 1. dragging and dropping the images in the APG Main Window 2. clicking on the "Select Images" button
Optimization settings are set when the group is created. So if you create an empty group (with "new group") we can't know that you will add fisheye pictures into it. So in this case general settings are kept. It's may be not ideal but this automatic fisheye preset (when possible) is helpful.
