Classify Rx for pharmacology

Hi Your app is really helpful and i really appreciate your effort If i were to give a suggestion to improve, it would be to add a highlight function to highlight specific drugs, as sometimes, as a medical student, not all drugs are required to study. Also it would be great, if there could be a little note/comment function on each drug, so that i could add some notes on it. It would be more helpful for my revision!! Thanks!
