Adds "other notes" field, cleaned up some code

The different program areas should have a colon, (`GA:` instead of `GA`) for consistency purposes, which can (again) assist screen reader software for the visually impaired. Also, the tab order should be set so that the cursor easily moves from one field to the next without jumping around. (Looks like you added this back in based on your original dialog, instead of the one I modified a few hours ago.)
