Hi all,
I have only answered to list.

The user will be able to change display name without affecting the 
internal name. The current solution of "paste always to the active 
layer" produces the problem described in the linked comment".

So do not generate a new layer "Foo" on page 2.

 If the user copy/pastes a group, all objects are taken.

That is the purpose of a group. But you can have this situation
Page 1
  Layer "Foo"
   Shape_1
   Shape_2 (contained in group1)
  Layer_Bar
   Shape_3 (contained in group1)
 Page 2
  Default layer

So group1 contains shapes from different layers, see description in the 
linked comment.

 And we need a separate function for the layer. So copying Layer_Bar

There is currently no option to copy a layer. We have not yet considered 
such option.

 into page 2 adds it likewise when creating a new layer and pasting 
just all objects from Layer_Bar. Differently to the ctrl+a,ctrl+c/x 
interaction, I would include all hidden elements too for the layer copy 
action..

There exists no hidden elements in Draw/Impress. Visible/Not-Visible is 
a property of the layer not of the element.

But you are right, copying an entire layer sound like a useful feature. 
That would be an option "paste and force a new layer for the clipboard 
content".

Kind regards
Regina
