Just a few things....
Want the reminders to pop up on my lock screen and to leave a notification number on the app when viewing from home screen. Also would like being able to pick pictures for locations I often visit (like work) and for personalized goals. Also would like dots on days I have events planned on the monthly calendar like the apple calendar does. It would be nice if the app had the actual day on it too from the home screen. Otherwise its fantastic!
