The featured posts widget will be the easiest option. You can have 4 posts on a row, you’ll just need to adjust your css. To do this, look around line 1360 for this –
#home-feature-bg-alt .featuredpage .page,
#home-feature-bg-alt .featuredpost .post {
float: left;
margin: 0;
overflow: hidden;
padding: 0 0 5px;
width: 300px;
}
And adjust it to look like this –
#home-feature-bg-alt .featuredpage .page,
#home-feature-bg-alt .featuredpost .post {
float: left;
margin: 0;
overflow: hidden;
padding: 0 10px 0 5px;
width: 220px;
}
…you can adjust it more if you need to.
