I like that you can use it as your own private page, or have others access from any where through their devices without having them login - which makes sense since this site was made specifically so they could keep track easily at home! You cannot add new pages/pages are not easy enough when someone wants one added by another user (you).
It doesn't seem there's much room left once all things get put into place unless more features were needed than just adding information about diseases etc., but overall its useful if used correctly because people do need help keeping up-to date info regarding illnesses & medical conditions out here during COVID times!!
