This is a very nice first web app. Congratulations, you've done fine work. I will offer one UI design tip. The radio button for All and check boxes for yes/no, etc under the filters tab is not how these ui elements are typically used. Checking Yes and No is all, so there is no need for the All option, just have all the check boxes checked by default and allow the user to uncheck the ones they don't want to see.
