In the configuration page, the options are split up into sections.
To expand the section, all you have to do is click on the titlebar of the section.
Well, I only figured that out after stupidly clicking non-stop on the down-arrow part at the right of the titlebar of the section.
So, either you should get rid of the down-arrows or you should make them act just like the rest of the titlebar (and like the down-arrows in the left sidebar of the entire WP Admin interface)
