Although it might be helpful to players I don't see it being needed. Also, personally I view mini-modding as; while staff is in the lobby and NOT afk someone saying "if anyone needs help please ask ME questions" or stating they're staff. Answering questions doesn't deem you as mini-modding. But only a few of the staff go afk in lobbies, if I'm mentioned in chat I get notified and switch back to answer if I'm not somewhere else in my house. But yes players are allowed to help others to an extent.
-I do like this, however rather have it in the vanity menu exclusively for staff due to timer possibly not kicking in yet and someone asking questions without the x number of minutes having passed.Would be nice if there was some kind of (if possible) particle effect that activated after x amount of minutes. Could look like little 'z's coming out of people (sleeping). If that could be created it would be cool :) You can turn it off in settings.
