As a user I would like to filter term types in the term list, so I can select the type I am interested in (e.g. titel).
When I am at the bottom of the languages list I see a toolbar with a button that has a 'filter' icon
When I click the 'filter' button
then a section after the toolbar appears and the 'filter' icon changes.
It shows a list of term types and checkboxes.
When I select/deselet a termtype
then the list of terms above is updated.
When I click the 'filter' button again
then a section after the toolbar disappears and the 'filter' icon changes back.
