Yousuf pointed out that objects from different parts in the hierarchy can 
belong to the same layer. So the layer is not part of the hierachy and cannot 
accurately be shown as such. It can be shown as a column in the 
page/group/object hierarchy though.
For layers, no separate view needs to be invented, there already is one: the 
tabs at the bottom.
