Sucks if you just want to sort by date modified

I added this plugin because I needed to sort my events by when they were posted (or last edited), to view the most recent submissions. After installation I realized it does NOTHING – you have to read their documentation, which is really complicated and confusing, and basically it tells you to go write your own code in your functions file according to their formulas – but supposedly this plugin is required before adding your own code will work. It is INSANELY frustrating.
