New layer creation rule

[AndRo Marian]

1. When i draw with the Pen in Designer its creating a SubLayer automaticaly.
2. When i create a new layer its added to root above to selected layer.

I want to create the layer above to selected layer.
Ex: Background -> Bubbles -> Red, Layer selected: Square.
I want to create the layers above to Square not to root or a SubLayer if is with Pen.
