I'd love to see some options for what files keys are allowed to access. For instance, there's a "Hide this File" option, but imagine if some keys had a "Access Hidden Files" option. This would be an excellent way for beta testers to access content that, say, is locked out for regular customers. Or perhaps keys can be set to link up to specific files instead of the full project. Would be a convenient way to not have to make multiple projects when running any kind of test.
