I found another issue yesterday when trimming surfaces you get an error pop-up which you can't exit out of and have to kill solidworks from task manager.
Reported to my VAR and it's just been found as a known issue so along with being unable to import certain step files and the obvious well documented user interface 2016 in general has not been great let alone SP2.0!
