I have just installed commerce to list a few products, but I don't wish to use the support feature for now. I have disabled it in ACP>Apps>Permissions but it still appears in navigation - albeit when clicked it says no permission to view it. Is there a different way to disable this part of the commerce app so that it doesn't show in navigation bar at top, as I may want to use it in the future.

Delete or remove the permission from the tab (menu) in Menu Manager.

Wow - that was easy - thanks so much Adriano!
