Thank you once more Sam! Much appreciated.
I know it is not the same, but in a way, your first point is somewhat doable already. I mean, you can draw outside the frame – or stamp down floating selections outside too. Then pick it all up and scale it down or move it gradually into frame again if needed.
Layer groups has been mentioned by others too. It makes a lot of sense – and it is on our todolist for future releases.
Cheers,
Niels
