One of the main purposes of Item Buckets is to contain a large repository of content items, without dealing with the normal structure in the content tree. With this said, displaying these Hidden Items would be unnecessary because they are auto-evaluated and placed in a folder structure that is formatted for you.
BUT I came across the problem where if Hidden Items in the View tab is unchecked, the Templates folder disappears.
Is there a setting either in the Bucket Item config or a base Sitecore setting that can be set to display Templates while using Item Buckets?
