What problem does this address?

It is difficult to know where on a site a pattern is used, and if it is safe to delete a synced pattern without causing missing content on the site.

What is your proposed solution?

I'd like a way to see a list of all pages, posts, and templates where a pattern has been inserted. This shows me how often each pattern is used on a site.

This will also show which pages will be affected by deleting a synced pattern.
