I just tried out the new remove tool in the latest update. I was very impressed. Is this the feature you are referring to?
You right click on the bandaid icon and select
remove. Then paint the area you want removed. It automatically fills in based on the surrounding background. Here is a picture that I didn't like the tree trunk behind the beak of the left heron was causing the beak to blend into the tree. I tried getting rid of that using several different tools, without much success. (I'm not very knowledgeable in PS.) This did a phenomenal job, very easily.
The original with the beak overlaying the trunk.
The edited version removing the offending wood.
I have several photos that have annoying content that I couldn't easily remove. I will have to revisit them and try this feature out.
