In old Fusion, when choosing the options in the sidebar (i.e. documentation to see due dates for progress notes, reassessments, etc), the calendar was still visible in the middle of the screen. In the update, all of the document reminders now pop up in the middle of the screen and the calendar is no longer visible simultaneously. It was helpful (in old Fusion) to be able to see both the calendar as well as the reminders simultaneously as it makes it easier to edit appointments, etc (rather than having to switch between screens).
Reminders - it was easier to view reminders when they were listed down on the left column, now we have to click (example: Rx Expiration's) and it takes the schedule off the screen. List of the left side were easier to manage. :)
