Not sure if I'm missing something here, but here's my experience: Going through the list of items to research shows you how long each item will take to complete. If you add two or three to your queue, then you no longer have the ability to tell how long the research time requires until that item in your queue starts researching? It removes the time requirement listing both in the research tab, and in your queue tab. Is that on purpose - we're supposed to write it down on paper before adding to our queue?
