Great idea, this program could be really useful, I'm trying it out right now

Just a few things: I find entering assignments a bit tedious, but I suppose that can't be helped...

The 'duplicate' button works fine, but once clicked, the assignment is deselected. This makes it a little hard to make, say, two copies of something because you have to hit 'duplicate' then re-select it, then hit 'duplicate' again. I would like to be able to hit 'duplicate' twice.

Also, the 'In Progress' button shows all assignments that have not been completed, in spite of whether or not their "start date" has arrived. I suppose this would be useful, but it's a bit overwhelming if I enter all my assignments for the semester at once, now I have to look at a long list of everything instead of the things I can be working on right now. Making a smart group would work, if operators like "begins before today" would work, but one can only select static dates.

Anyway, keep up the good work!
