Change month in events+ calendar

Hi,
I'm using the Events+ plugin with the included shortcode "[eab_single]" as a calendar.
Now I'm missing the function of navigating through the months. What I would like to see is a navigation element on the bottom (or top) of the calendar with the month and navigating arrows on either sides so you can navigate through the months.

Is there a way I can implement this mysef by simply changing the plugin files or is this way too much work?

you can see what I mean by the calendar in the sidebar here http://4h.notater.net
