I'd like to be able to remove relationships from the main topic view window, as shown in the screenshot attached.

The scenario that this would benefit is in maintaining topics, such as per the screenshot where I've rejected a topic that has eventually been overlapped by another topic's development. 

Under the current system I'm having to note the related TopicIDs, go to the search field and add all the topics that I'd like to populate the results of the relationships screen. Here I'm able to remove or otherwise manage the relationships.

For the sake of removing rejected topics from a family of relationships, this would be handy to do from the single TopicID list screen. In this case, I can simply search for one topic, and ideally click to remove the listed relationships from there.
