The new gradebook in Moodle 1.9 has some usability issues. For one, when you go to the gradebook, and use the drop-down menu on the upper-left corner (Choose an action) and select Edit => Categories and Items, it would show you this screen (see attached screenshot). There are three buttons on the bottom, but the "Synchronise legacy grades" is a bit confusing and I think we could add an extra help button right next to it to explain what it would do, what do people think?

Just my $0.02...
