[Plugin: Featured Page Widget] How can I edit the title font size and alignment?

I’m wondering how I can make the title font bold, larger and align the title centrally in the featured page widget? I’ve had a look through the .php pages for the plugin, and also my theme’s .css but I can’t find anything obvious.

Also, how can I add a ‘Read More’ box (like the featured blog boxes have)?
