A great feature would be the ability to override an existing page slug when creating the new page in EComposer.

Without this, I'm forced to create a page like "about-us-2". Then I need to delete the original page, go back to EComposer and edit the slug to the desired slug "about-us", then go into all the Shopify Navigations and update those to point to the new page.

This is especially troublesome when we are also working on an unpublished 2.0 theme upgrade, forcing us to update the Navigation in two places.
