Use case or problem
The outgoing links plugin (especially the unlinked mentions section) is practically unusable when working with a large file within a large vault. It is too tedious to scroll through a long list of unlinked mentions for identifying potential connections to other notes.
Proposed solution
The backlinks plugin has more functionality than the outgoing links plugin. The backlinks plugin has the toolbar that allows you to search, and the unlinked mentions are organized by the parent file. Please add the same functionality to the outgoing links plugin that the backlinks plugin has. Doing so will improve its usability and make it functionally consistent with the backlinks plugin.
