I have a 256×256 image with multiple named layers to make it easy to edit game graphics that have transparency as PNG. I want to paste the contents of one layer to the next... so I select the source layer and use Shift-click to make all others invisible, then press Ctrl+C, I then go to the next layer up Shift-click and then paste - but it inserts a "floating layer", I'm misunderstanding something basic here.
I have installed the multi-layer-exporter plugin so my layers all export from the xcf as PNG's. I just want to be able to copy / paste layer contents/pixels. I imagine I could just rename the "floating" layer as a layer, but I want to mask and copy between layers often.
The floating layer is special somehow, what is the intention of the "floating layer"? I am unable to merge it to the layer below, so it is being treated differently to a normal layer.
