Just downloaded OGP5 beta and it looks like a very nice improvement. I like the use of Shared Layers in place of Master Canvases.

Are there plans to add sub layers or layer groups (similar to Photoshop) in the future? I find this immensely useful in Photoshop when designing complex prototypes. I was really hoping to see this in OGP5 but it doesn't look like it's there and I don't think shared layers will accomplish the same thing.

Is this a technical limitation or a philosophical one?
