Tags section - Linked Journeys / Tabular Format

The linked pages feature is cool but could we also have linked Journeys. 

The below tags aren't linked to a page/campaign but are the starting point of a journey so we couldn't use this as a way to delete un-used tags easily.

It would also be great to view this in a table view (similar to offers) and be able to filter and easily remove tags no longer required. (Mass delete etc)
