Assignment Groups Detailed

I am nearing the end of my first semester using Populi and loving it!  I will have more time in the coming weeks to look into features I am not aware of yet.  The feature that I would like to see would be the ability to sort assignments by groups in the individual student view in the roster area.  What could also work would be a way to do a pdf summary (and there could be an option to sort by date, by assignment group, etc.).  I used to use a program called Maplewood and I like everything about Populi better, except I miss that Maplewood feature (by default they had assignments sorted by groups - they also offered sub categories and sometimes I would group units within a group).
