“This plugin adds a new view type that can be selected when adding job views. This view does not show any jobs, but rather contains another set of views. By default, clicking on the view tab for a nested view shows a list of the subviews it contains (with folder icons). You can also configure a default subview to bypass this intermediate page and jump directly to that default view. Now the view tabs across the top show the views in this nested view, and the job list is for this default subview. This streamlines the navigation between views, but makes it harder to find the Edit View link for the nested view itself. Once a default subview has been assigned, navigate to the edit page by first clicking the plus (“+”) icon in the view tabs (for adding a new subview) and then find the Edit View link in the sidepanel.”
Nested View Plugin is a very useful plugin to maintain a friendly view structure.
