add techprint information

How am I supposed to see what Techprints I have and have not installed already? Am I missing something? I looked in your mod options and I don't see anything to toggle on the "0/2" labels on the research tags, and nothing gives the information when I hover over it. WheneverI find a techprint I have to exit, disable your mod, reload, check the vanilla tree to see if I need the techprint, then exit, enable your mod, and reload the game again... its really inconvenient, so I assume I am just missing something.
