OK, I've implemented the basic functionality for using your own nurnies.
If you select a series of nurnies in the background and choose 'Layers' from the panel type drop down, it will randomly distribute those background layers in place of the procedural nurnies.
What sort of controls do you want to see for it? Do you want to mix layers and procedural nurnies? Let me know how you want it to work.
When this is released, it will be a free upgrade to those who have Quadpanels already. There are some other features I want to put in there for you all too.
