The Encyclopaedia is a bit rubbish at times, you go to look something up you're interested in buying - say a Station production module - and you can't see it's stats yet cos you don't own the BP. Doh! With Ship modules it's easier as you can go into outfitting (like start the process of buying a ship) outfit it with whatever you want, then right-click > Encyclopaedia.
I think, when looking at ANY BP in the Faction Rep's screen, we should be able to right-click > Encyclopaedia there and get the full stats, which would then be added to our copy so to speak. We should not have to rely on external tools or memory to know what a Module we've not bought yet actually does.
