Hierarchical organization by video

It would be great if you could organize the saved content as a hierarchy of words and phrases belonging to the videos and series/playlist they came from. Keep the color coding as an independent organizer, but also allow us to export and use phrase pump on the content pertaining to one video or group of videos. But also have the option to draw from the whole hierarchy as at present. Or, at least let us select the color filter for phrase pump, so we have some control over what we are studying. I watch and click the works on multiple types of videos, but I would often like to be able to focus on one at a time.
