It’s a great plugin bit the view is a bit clunky if you are displaying thumbnails and exerpts. Try adding the CSS below:

/* ICENI CUSTOM CSS */
.display-posts-listing img{
    float: left;
    margin: 0px 10px 10px 10px;
}
.display-posts-listing li{
    clear: both;
    list-style: none;
}

This can be added at the bottom of a CSS file or through the GUI at Appearance > Customise > Additional CSS
