I find that often I will duplicate a set of objects or paths then send them to a new layer. However, in the drop-down menu and the layer menu for the selection, there are only options to move the selection up/down a layer or to an already existing layer. I can't just go create a new layer because then my selection is deselected. So currently, I have to anticipate that I will be needing a new layer (sometimes several operations ahead of time - because some chains of operations require that I don't lose my selection) and create it ahead of time. Is there a way to send a selection to a new layer?
What just worked for me was to cut the selection (CTRL-X), create a new layer, and paste the selection into the new layer. I agree that a "new layer from selection" command would be nice.
Aside from the keyboard shortcut, there are a couple of other options: 1) Select object -> Layer Menu -> Move Selection to Layer 2) Select object -> Right Click -> Move to Layer
I found that paste in place converted vector objects to bitmaps.
Hope this will help -
Create your layers, then select the object you want to move to another layer and shift+PageUp (to move 1 layer up) or shift+PageDown (to move 1 layer down)
