Hey @angus a big heads up here: the Review Queue is unfortunately going to have breaking changes for discourse-moderator-extension and discourse-category-moderator-lite since it removes QueuedPost.
I am working on backwards compatibility right now, and while some internal APIs can be preserved, the prepending of modules to QueuedPost and QueuedPostController will not work as I can’t cover the entire thing.
The good news is the Review Queue is meant to allow group specific moderation, so it’s likely the core functionality will meet your needs or be much easier to customize for them.
The feature is not ready for primetime, so I’m hoping with enough notice you’ll have a chance to review the changes coming to core to minimize interruptions.
