Less user privileges for editors and other user roles

I’m using W4 Post List to create all kinds of lists on a very active website, which has multiple content editors with various user roles and capabilities. I would like to prevent certain user roles (editor, author, contributor or custom role) from accessing or editing post lists created by W4 Post List plugin. It would be nice if only admin-level users were able to edit anything related to W4 Post List. I’m fairly sure that there are many others who’d benefit from this feature as well. Would you be willing to develop this functionality to the plugin? Thanks for your great work so far.
