Zoner software

Having recently embarked upon a departure from Photoshop elements, I am refreshed by the versatility of Zoner 18 and will be experimenting with the seemingly complicated range of refinement options which the Zoner 18 pro package offers. It is a learning curve, and the features seem derivative of other packages - but finding what you might need all in the same package is a novelty and I am so far pleased I took the plunge with this. Is anyone else doing something on similar lines? I have attached my first effort at optimization.

Not heard of this before but I shall look at it.

I believe that was a resizing gizmo I touched but did not reverse. Almost like a crop but I moved it inadvertently
