When a patient is on a list, we can see it from the patient file but we have to go to the list module to remove it from that list (and when we do click on the list name from the patient file, it brings you to the list but you still have to find the patient.... lots of clicks). Same goes for when you want to add a patient to the list from the patient file, you need to go to the list page and can,t do it from the file.
What if we had a small 'X' button or similar next to that list on the file?
Use case of lists:
No registered doctors at the clinic
Patients that owe money
etc
