Implement an Seam component scope and topology viewer/editor. This view should show all Seam components created by the user in their scopes(session, conversation, etc..) and the connections between them (@In and @Out). The view should focus on the way the seam components inject or outject components from the context variables in the different scopes, thus the scopes can have their own areas spanning finite width and unbound height graphically.
You should be able to drag components from one scope to another and create @In and @Out links between components from this view.
Referenced components that are not created by the user can be displayed in a "non-draggable way" (with a lock-icon or grayed out for example).
Additionally the built-in Seam components can be displayed in a toolbar similar to the UI controls palette, but with checkboxes next to them to assign visibility in the view (instead of dragging them into the view like UI controls).
