To copy layers/groups of layer between open files in Photoshop, this is what I do: drag one open file tab so it become a small window, then I can drag drop my layer between the documents. I haven't been able to drag layers to tabs directly.
This is cumbersome. Is there a faster way?

Highlight ALL the layers you want to copy. In your Layers panel, right click the layer and choose "Duplicate Layer." There will be a dropdown to choose the destination file.
