Openshift : deploy existing project automatically on OS app creation

When creating an new openshift application from an existing workspace project, I expect my project to be deployed automatically once the Openshift app is created.
Since not all projects are openshift-ready, we should have a checkbox on the openshift wizard (enabled when using an existing project) that basically says "deploy my app once created".
The state of that checkbox should be stored in the workspace preferences.
And obviously, when the box is checked, the local git repo would be pushed after the openshift app is created.

Workflow should be :

• create a project 'myapp' from JBoss Central (say HTML5)
• create a new OpenShift application 'myapp', based on the jbossas7 cartridge, using the existing 'myapp' project
• check the deploy checkbox
• once the myapp.<mydomain>.rhcloud.com server is ready, Opening http://myapp.<mydomain>.rhcloud.com should display the HTML5 app
