It is easy to get lost in the wrong week on the calendar for two reasons. 1) Today's Date is only highlighted at the very top of the page. 2) There are so many appointment times due to the 15-minute increments that the highlighting is not visible when you scroll down to later in the day.

Suggestions: 1) Highlight the entire day including all the appointment times with a background color. 2) Give options to collapse the appointment times to hourly or choose hourly increments so we can see the entire day's appointments without scrolling. This would also solve the annoyance of constant scrolling.
