In the research tab, it should show us specifically which item we have that can be used for each research. Not just showing which particular trait you have an item for. I want to be able to hover my mouse over the spot where it's showing me which research can be done and see which item I have that can be used for this. Yes, if you click research on that spot, a little pop-up will show that tells you which items you have that work for it, but this can't be done when you're already researching something.
“If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.” -- René Descartes
