I’m the publisher of the GIMP snap.
I would like to provide the ability for plugins, such as g’mic and darktable, to be integrated with GIMP without shipping them inside the GIMP snap itself. These plugins can be variously python scripts, binary libraries, and so on. Some of them require compilation. As such I cannot anticipate every dependency that they may require to ship those within the GIMP snap. I would like to allow third-parties to create and maintain their own plugins independently of the GIMP snap.
So the question is, how can I expose the GIMP plugin capability to third parties?
