Copying adjustments on layer and tool level

Copying the adjustments from layer to layer or even from tool to tool would be very useful. As you can copy the mask from one layer to another it would be nice to be able to copy the adjustments (without the mask).

Sometimes you made an adjustment in the tool which is on the background layer by mistake and you would like to quickly copy that adjustment and apply it to another layer. I'm aware that I can save the tool preset and load that preset on another layer and then delete that temporary preset... but that's cumbersome. 

While I'm here, here's one more. 🤓 Why don't you allow multi selection of layers. That would make editing, deleting, copy/pasting, enabling/disabling... of layers much easier. 

Please consider adding that functionality. 🙏
