Two questions:
1. Does WP Review Pro have some kind of shortcode to do the Masonry layout shown in the demo, or are you using some other plugin to do this display?

Does it only work on posts, or will this type of layout work on pages too?
2. Does WP Review Pro have custom themes or will I need to do my own CSS?
