What does the +AI symbol mean

There have been updates since I last used FM. When I drag images to my timeline, there is a little yellow +AI symbol on each of them. I was concerned that these would appear in the actual frames, but they don’t.
I have no idea what this is about and would like to be advised or pointed to the manual, where to is explained.
Thanks

The crosshairs with the AI indicate the point in the image that was identified as the “most interesting part” of the image by AI. Depending on the settings in the “Animation Assistant” FotoMagico will automatically zoom to this point, leading to better out of the box animations. Obviously this is just a starting point, and you can always manually finetune the animation if you wish.
