blackboard >:( (a rant)

I hate blackboard so much, why does it have to be like that? I've been using it for a couple semesters now and it never ceases to inconvenience me. If I click on a quiz or something from my activity stream, it doesn't give me the option to close out of that specific class, so I have to reopen blackboard after I finish that assignment so I can move onto a different assignment for a different class. Also, it's not easy to navigate if you've never used it before.
