Hi,
Shopify could make improvements to GitHub integration. First of all commits description should include not only shop, but author of changes. So we could know who exactly made changes. Second thing is that we should have more control over what is pushed from shopify, eg. only config and translations.
I would also love to see something like this. Having 20 editors changing content within the theme editor and also have access to edit the theme files directly in shopify is really hard to debug, who made which changes. And the commit messages are really redundant and not really helpful. (because its missing the author e.g.)
