Hello, let me tell you an idea I know. I think it will be very useful. If you do not have Redo undo in Photoshop, then there should be no change in the middle layer, which should be Redo and Undo only in the specific layer that we select. It would be nice to have an update like this. Generally use ctrl + z and ctrl + x. It would be nice to have ctrl + (your suggestion word) + Z and ctrl + (your suggestion word) + x to Redu and Undo the specific layer I mentioned.
