Adobe AIR flow designer like Nokia Flowella

I want to add "Flow designer" functionality to my existing designer application. Currently I have a designer application where the user can drag and drop components to a page, I will also let user create multiple of such pages. Flow designer - is a new component on the existing application, allow the user to connect multiple pages using drag and drop UI. ------ workflow----- 1. User will design the pages using the current designer, He will create as many as pages he wants 2. After this, user will open the flow designer (it can be a menu from the main app) 3. This will show flow designer screen, with all the designed pages 4. User should be able to draw line from one page to another page to show the flow , like Click of a button , select of combo box, So here the user will click on a Button on one page and draw line till next page (drop on top of another page in the designer) . This mean when the user click on the button (real app), the target page will be shown 5. User should have the capability of adding transitions , like, Flip, slide, dissolve etc This will be similar to "Nokia Flowella" <[login to view URL]> ## Deliverables Attached screenshot of my current application
