Todays upgrade seems to be a downgrade! Game has crashed repeatedly and when running is slower than it's ever been, even after I adjusted the quality down to low. Hopefully the developers will get this fixed as the game itself is very good!
To get the students you want grouped together or on top of your list or whatever, just rename them - the list gets sorted alphabetically each time you open it. All my low level chars have names starting with Z :)
