Having multiple .c3p files without control version would suck until git , it would be nice to load from a git repository to edit the games or the plugin and having the control of versions if it's possible.
We could push the changes directly to github, server or scirra cloud service.
Looking at the api it should be doable.
Something that might be quite interesting is possibly publishing to Github pages.
Develop games in your browser. Powerful, performant & highly capable.
Bundling it in with something like Jekyll would be very interesting for Github pages, but I have no idea how that would work with Ruby
