I have chosen to not use SEF in my J31 design (it is intranet, so seo is not an issue for me). I have found that when you turn off SEF (in global config) the javascript expanding event list fails (in calendar grid view like this - http://demo.mintjoomla.com/en/calendar.html ) All of the color markers disappear, the tab and expanding black event lists do not work. I am attaching a screen shot of the features that do not work in non-sef mode.
