Well, this looks quite interesting. I've never used a node-based editor before and I've been using Photoshop since the 90s, and haven't used much else so I don't know what I'm missing.

I took a look at the demo and at first glance, it looks like the current version is just a basic image editor. I don't see any options to add noise, blur, filters, etc.

Also, curious to know about the graphite fileformat. When editing an image, are the set of transformations, etc. suitable for version control?
