Please add an ebuild for Natron. https://natron.inria.fr/ "Node-graph based , open-source compositing software. Similar in functionalities to Adobe After Effects and Nuke by The Foundry."
Many ebuild requests remain open for years, because nobody maintains the package. If you want to be (proxied) maintainer of this package, please contact the proxy team [1] and prepare an ebuild [2]. You may want to link your repository [3] or attach the ebuild here until it makes its way to the official tree.
