Hi, this module sounds great. Have you talked to any of the devseed guys about this, bc I'm pretty sure they've discussed having this in the core features module, if I'm not mistaken. Not sure about that, I just remember talk of it before.
Anyways, on to my feature request, if it's not already a part of what you're building. It would be amazing if disabling this feature removed all the corresponding content that was created by it, if the content hasn't been overridden. So, if you disable the feature, for each node the feature creates it checks to see if that particular node has been changed, and if not the node is deleted. Does that make sense?
Thanks!
