Would like new feature " useful for teachers"

I teach high school geometry, and one thing that would be very useful is the ability to organize assignments in efficient ways. For example, After the first semester I would like to be able to move assignments that I had assigned into a folder that I can label called 1st semester, so that they still give credit and I can still go back to them when I need to, but I don't have to dig through lots of assignments in a class just to find the one I am currently looking for in a new grading period. i.e. I don't want to delete those assignments but I also don't want to have to dig through them all whenever I am looking through assignments especially when I am grading. This feature would cut down the time I spend grading probably in half. In addition, it would be very useful for me to be able to just drag the order in which I want the assignments to appear on students assignment screen instead of having to game the due dates so that the assignments appear in the order I want them done. I would prefer to not set a due date for any of them and just be able to set the order in which they appear
