I just got the new Meta Navigator UI update. I've been using heresphere for years. I dont see anywhere to enable 3rd party sources /view 3rd party sources. I can see that the application is still installed. Any suggestions? 

Figured it out, In the new UI look at the left hand side. There should be 3 vertical buttons. One of those will lead to a list of installed 3rd party apks. Click the name there to launch.

so silly. Thanks meta :/
