There do seem to be some improvements in V12 with regard to the "favorites" in the eRx module. I have just gone from V11.1 to 12, so maybe some of these are older and others know about them, but to me they are new.
1. When selecting a medication from the "Current Medications" list on the left, the fields on the right are populated with the full sig of your last prescription. No more hovering over the old one to remind yourself of the actual sig.
2. Favorites can finally be customized. In particular, you can delete the ones you do not want. Type in the name of a new medication and the favorites previously saved are at the top of the list as you continue to type. There is a little red x at the right, and if you select it, the favorite is deleted. (I have found it hugely annoying that 5 or more favorites show up for a given med, cluttering the screen and diluting the advantage of having favorites at all. Now I can keep the one or two sigs I want).
3. I think that favorites are added by default after you prescribe the medication, though I cannot verify for sure how the selection is made. It would be nice to have a button "add this rx/sig as a favorite". (Hoping the new way they are added beats the old system where no one could explain exactly how a favorite got on the list - apparently by some algorithm based on how often you used the med and the sig).
Not huge changes, but welcome ones.
