When my asthma plays up and I want to record pre and post salbutamol peak flows as well as my usual morning and night readings. I have to go to add a spontaneous measurement, then search for PEFR every time, despite being presented with a list of most common measurements which are irrelevant to me. Could that list be personalised, either by letting the user choose their own "favourite" measurements or automatically generating a list from the individual users useage/behaviours?
