First, I really miss the ability that the older products like Gigapixel had to compare two versions of the settings. It can be hard to tell whether a setting adjustment was an improvement or not. Please implement this for Photo AI, too.
After that, what would be really helpful would be to implement a means to blend the two edits, because often one part of the picture looks better with one set of settings, while another looks better with other settings. This could be something like painting a layer mask to make the top layer transparent.
