Once a request is made if the app is stable and can be added without causing issues to other app's we will do our best to add it when we do system updates. No ETA's.
Tickets are acknowledged/Closed after request. Please do not bump/re-open to nag for it to be added. We can not give ETA's or updates. When/If new apps are added an announcement will be made with details.
