Time based lists should be in DESC chronological order. Examples where this is not the case presently are;
a) Patients->Medical Records->Summary Tab->Visit->Items (eg. Notes, Medications etc) Ideally these would sort in reverse chronological order and in groups of type (ie. Medications, Notes etc). The need for grouping is largely obviated by the ability to filter but date ordering should still be in DESC (particularly for notes).
b) Edit Visit Dialog->Medical Record Items (eg. Notes, Medications etc)
