Feature Request: Hide all single line entries on Home Page

This is a request to be able to show only those items on the home page that have sub-items under them. I would like a way to filter only those on the home page, so that items consisting of only a single line (no sub-entries) are hidden.

Currently there is no search operator to filter these out. The use case is that items with sub enties are more meaningful projects with more content and can get buried in the clutter of the other entries occupying the Home page.  Thanks for considering it.
