[AP] Please improve curves editing in Affinity Photo

[IPv6]

The curves editing (pen tool, node tool) are generaly fine and convinient, but there is two small features that should increase quality of life:

1) please, add the ability to cut/copy some curves from one curve layer and paste them into another curve layer. Current way on breaking the curve and joining them back is unusable for layers with many-many curves

 

2) There is "Add new curve to selected curve layer" option for pen tool. It works fine, but it should also work when adding curve to the MASK of curve layer. Because for now if user want to erase part of curve, switch to eraser tool, erase parts (mask is added by assistant) and start add new curves - pen tool adds new layer, since it is mask layer selected. While this is obvious that in that case curve tool should jump back to mask-parent curve layer and continue to add curves here, always
