GIMP 2.8 Python Plug-in.
Copy and move the selected area to a new layer in the same position.
This function is similar to the functions with the same names in Photoshop, and more powerful. Unlike them, it can copy/cut content, not just from one layer, but also from the layer groups.
In Photoshop, this is not possible

Installation:
1. Close GIMP if it is open.
2. Extract "layer-via-copy-cut.py" from zip archive to the ".../.gimp-2.x/plug-ins" directory.
3. Run GIMP. The script should appear under the menu: "Layer > Layer via Copy" and "Layer > Layer via Cut". Don't forget to make the plugin executable.
