There is a context menu item to import an existing OpenShift 3 application available on every tree item placed under OpenShift 3 connection. Even "folder" for any resource has it (e.g. Routes, Services) and any resource too (e.g. specific pod, service, replication controller).

I think this is not good because it go against concept of context menu. We could have it for a project and build config (maybe also for a connection) that would be sufficient.
