I think more classes or tutorials on how to use the various tools available in PSP. For me, it doesn’t do any good to have some of the classes that focus on making something specific if I don’t know how to use the tools needed.
I have used the clone and scratch remover but not sure if I’m using them efficiently. I’ve never tried the object remover. Of all the brushes, the only one I use is the burn brush… I’m not sure about any of the others (like lighten/darken) because if I do use them they don’t seem to do what I think they are supposed to do!
I also struggle with the other brushes like chalk, oil, crayon etc.
