There's only two, but there could be a lot more. I've used a lot of your editing tools to capture what I'm attempting to create.
Adding blends such as: neon colors, automatic borders/outlines for cropped pieces/background removed images (with an option to make the border/outline neon colored), an inversion blend with adjustments (I know you can invert, just separate from the looks feature and more editing features),

Adding editing features to automatic background remover such as manual removal tool (if it's on there I may not have used it yet)

More control over blending images/art via smudge type tool, blending tool, dodge, etc.

I'd like to be able to stretch, transform objects, freely too.

Being able to have different styles of brushes to use plus manual eraser (if it's on there I haven't used it or seen it yet) I know it's on PC.
