As per IMC (and Julie working as best as she can to get information) only the Exp Viewer and Fog Viewer have been officially approved. Julie has mentioned in other posts she’s brought up some others to IMC so far.
Additionally, Julie “liked” my post which implies not only that she read it but that she agrees with it, meaning we may see a sub-forum in the near future with pinned threads regarding approved or denied addons (assuming she gets the go ahead from IMC that an official process is something they would want, because creation of a sub-forum is well within her power already).
