Atlas UI for classification (index.html#!/tag/tagAttribute) currently lists super-types of the classification - if the classification has any super-type. It will be useful to list sub-types as well.
In addition, listing of classifications in a hierarchical layout, instead of current flat listing, would make it a lot more usable. Changes introduced in
ATLAS-2283 would provide necessary details for above UI updates.
ATLAS-2020 added "entityTypes" fields to classification, to specify entity-types for which this classification can be applied to. It will be useful to include this detail as well in classification details page.
