We're in the process of refactoring a whole lot of code from the pre-node graph MVP implementation to the node graph version, while mainly aiming to avoid losing functionality in the process and not prioritizing new functionality quite as much yet. You can import or draw an image, though, and then right click in the node graph and search for certain effects and filters (similar to Photoshop's adjustment layers) and insert them in the chain of nodes. But to become actually useful, we need a bigger and more thought-out family of nodes combined with tools which automatically insert and update the nodes for you through the means of using the tools and doing lasso/marquee-style selections. Those are all a few months away on the roadmap, but it should be a lot more powerful and novel by then. The file format will have its own built-in version control in the future, but I believe we are planning to use an ASCII representation so it could also theoretically be version controlled externally. The current `.graphite` files are entirely a temporary format. Once we finish the aforementioned refactor, we will design and implement a proper file format that ensures backwards compatibility (something the current files don't manage at all), it will be called `.gdd` (Graphite design document).
