Last client button

It would be super helpful if up by the search for patients on the calendar page, there was a button you could click to take you to the last client file that you were on. Instead of having to type the name back into the search, it's a simple click back to the file... :-) This would just be for the very last file. I had a similar feature on another system I have used and it allowed for you to see the last few files visited but just the last one would save so much time!! :-)
