Confluence by Thierry Dalon

This Extension is a great add-on to Atlassian Confluence, both Cloud and server/ data center versions.
Main feature allows to quickly search or open Confluence pages supporting label combination - which is not available in the Confluence built-in search UI.
It also provides additional features like Heading numbering, Copy nice link, Copy breadcrumb link, quick open spaces, label dictionary and snippet manager.
