It would be nice when Logos 4 adds a vocabulary list feature if we could right-click on a word and have it added to a specific vocabulary list. So if I am reading through a book in Hebrew or Greek and I come across a word I don't know I would like to be able to add it to a list for review later (and later I could delete it or de-prioritize it once I've gotten to know it). Also, that list should be sortable by frequency, so I can ask it just to show me words that occur at least 10x and then once I know those go into the rarer words that I've added to my list.
