Hi Alex,
In the AEM6 Mobile Feature Pack (FP1) hosted on Package Share [4], we removed the ability to create an app from within the Apps catalog view. We expect users will leverage the kickstart apps we've posted on github [0] to learn and create custom new apps. The expected workflow is to copy (or fork) one of the kickstarts and using Maven, deploy into your local (or remote) instance of the AEM6 (FP1) quickstart using the command line, "mvn clean install -PautoInstallPackage" (see the readme with each kickstart for specifics). The benefit of this approach is that we help bootstrap your development environment and supply an easy command line method to vlt into your quickstart. Alternatively, you can edit the Geometrixx Outdoors reference implementation we ship with the release (note there is an update to this on package share as well [3]).
