Navigation Component questions & possible enhancements (Banzai)

The new navigation component is a great addition to the Skuid component library.  In working through the feature, I encountered a few questions, some of which might have answers or possibly turn in to enhancement ideas/requests.

1) Is there a way to “fill” navigation items directly from a model?

2) Is there an API for the navigation component to add/remove/etc. items?

3) Is there a way to have a manual menu behave like “required” meaning that one of the items would be the “active/label” instead of a separate “caption”?  Would be similar to the way “Salesforce Apps” doesn’t have a caption it is just whichever “app” is active.

4) If #3 is possible (or could be added), is there a way to indicate which menu item should be “active”?  For example, a custom navigation menu built without salesforce apps/tabs would need to show which one the user is on (similar behavior to salesforce apps with a way to indicate how to tell which is the current item).

5) Is there a way to set the “_target” for menu items that comes from stock lists (salesforce apps, tabs, etc.)?

Thanks!
