Feature Request - Custom Layers

[nicolassargos]

Hi again (cf post below),

I'd like also to propose a new feature : custom layers.

You could assign some nodes or any Model object to those layers and reorder them, so you could have custom buttons on top of the diagram. I, for example, have a custom menu (spacebar that shows rounded menus), but for now, they are behind all other layers, as for now, I think only Links & Nodes layers stack level is configurable.

If this already exists, obviously my request is moot and I'd love you to point me into the right direction. Otherwise, I think that would be a pretty handy feature.

Have a nice day,

Nicolas Sargos.
