It would be nice to have feature to create a new resource, e.g. image stream or pod, from provided json. Similar to "oc create -f some_resource.json"
Currently it would be very usable for MW application templates, because jboss-eap basic s2i template requires image stream which is defined in another json. Also there are applications which are consisting of separately defined resources (e.g. in openshift origin repo is hello world application and its having defined pod in separated json).
This could be available via context menu New - Resource (like we have for application, projects and connections). And it could be accessible via context menu of a project and specific resource type (e.g. for tree item Image Streams).
