As a <user> I want <drag and drop tags> so that <they are easier to manage>

From George T on slack:

> it'd be great if you add a Drag & Drop option for tags in the Time Stamping Tool. For instance, when we want to remove a tag from the Middle Relevance section and add it to the Low Relevance, we have to copy it or retype it. It would be a more efficient and fast way of organizing tags. Hope others will find this suggestion helpful as well.
