Entries Spacing Help

First off, Great script, its perfect and exactly what I'm looking for.

Is there a way to put a BR tag or something in between entries? I really would like this because I think it looks nice, specially with my site.

An example would be found here

I'm pretty familiar with PHP, so finding the code isn't too much of a deal, I just need to know which file etc...

Thanks guys/support!
