The most important cropping feature of any program is to crop out any image of any contour or shape. Can this program do this? Can it crop out, say a photo of a tree around all its branches?
Welcome to the forum. The term "cropping" has a somewhat different connotation as it is applied in this program.
You can use one of a number of selection tools, or a mask, to isolote an object from it surroundings.
Yes, it is possible to target a tree with its arborization , copy/paste it, change brightness/contrast, etc.
If we are talking selections then PSE11 has the refine edge tool which is specifically designed to deal with complex selections such as human and animal hair and tree branches.

I don't see a "mask" feature. The Magic Extractor worked great to select and crop out an evvergreen tree. But where is the button to click after I select "Want" or "Polygon" tool or "Magnetic" selector to crop it?
