Well, I noticed in the newest version of AC that the recent Vital signs are displayed (& that's really helpful when you want to know how the patient's weight or BP compares over the last few visits) so I would like 1 or 2 customizable spaces in that vital signs section to track: A1c or INR or PSA or Hgb.
BUT: I don't know if this would then be available for graphing or reporting (a la P4P). I'm also not sure how this works with the lab interface.
