[Plugin: Blog-in-Blog] how to show default WordPress posts formatting?

Hi,
Thanks for the great plugin. I was wondering if there’s a way to use WordPress’s default nice looking formatting for displaying posts.

Here is my website: http://msflights.net/ As you can see after scrolling down a bit, the formatting of my posts don’t look to great. I know you can change this with templates, but i am wondering if there is a way to use the default WordPress formatting when displaying posts? The default WordPress post page shows authors avatar and name in a box, with the date, along with line breaks in an attractive format.
I would love to use this formatting,
Thanks!
